Nitric Oxide Supplement Side Effects – Is Nitric Oxide Safe?

Nitric oxide supplements (also known as pre-workout supplements) have recently become popular and are now a craze among weightlifters in the gym and athletes on the field. Nitric Oxide Supplements are used to initiate an increase in blood flow through the veins, delivering nutrients to the muscle as well as giving its users incredible pumps and strength in the gym.

Properly using nitric oxide supplements as pre-workout supplements does indeed bring the benefits listed above, along with others not mentioned here. But Is nitric oxide safe? Are there any nitric oxide dangers to be concerned about?

The answer is that it really depends on what products you are considering taking. Each pre-workout supplement contains different ingredients, and it’s important to look at the entire profile to see what may cause problems.

  • Nitric Oxide Side Effects: L-Arginine and AAKG

    The first, and most important ingredient, is arginine. It’s often packaged as L-Arginine or AAKG (Arginine Alpha Ketogluterate) in nitric oxide supplements. This is the amino acid that initiates the the NO gas drive into your muscles, giving you the full-looking, pumped feeling thanks to its ability to open up your veins and increase blood flow to the muscles.

  • AAKG research studies have shown that arginine and its variations are extremely safe, even after doses that far exceed what is typically found in your average pre-workout supplement. Nitric Oxide is a naturally occurring molecule in your system, and getting your body to produce more of it has not shown any highly negative side effects. Go too far above and beyond the recommended doses, though, and you might get gastrointestinal distress. The main purpose of these supplements is truly safe and there are no nitric oxide side effects from AAKG unless you’re taking half a bottle of the stuff. However, there are still some other typical ingredients to think about.

  • Nitric Oxide Side Effects: Creatine

    Most pre-workout supplements contain some form of creatine. Despite what some people may think, creatine has been proven to be extremely safe and effective, even over long-term usage (Creatine Side Effects). We always recommend going with standard creatine monohydrate, as it’s the most common form of creatine, is inexpensive, and has had the most safety research done upon it.

    However, taking too much creatine may cause side effects of diarrhea or cramping, but that often only comes when taking very large loads of the substance – far more than is typically put in nitric oxide supplements. The days of “creatine loading”, where companies would tell you to take over 20g of creatine each day for a week (in order to sell more creatine!) are over – it’s not necessary and may lead to diarrhea. But it’s still important to drink plenty of water when using creatine, and be careful if you’re adding more creatine to your post-workout drink. If you are adding more, start light, perhaps by adding another 3g of creatine monohydrate powder post-workout, and assess from there.

  • Nitric Oxide Side Effects: Caffeine

    Caffeine and other stimulants are often found in nitric oxide supplements. And yes, these stimulants can and do have some side effects when not used properly. They include irritability, loss of sleep, fatigue (from the caffeine crash), headache, skin irritation, higher blood pressure, dry mouth and water retention. If you are very caffeine sensitive, don’t start with a full dosage of your nitric oxide supplement. Also, don’t take it too close to bed if you’re planning on getting any sleep – we make sure not to take these products after 6PM or so, but it varies by person.

    Caffeine is safe in small doses, but overdosing can occur if mixing pre-workout supplements with other stimulants, such as coffee. Additionally, caffeine is addictive, and you may get withdrawal symptoms when you stop using it for a few days. Such symptoms include fatigue and headaches – but they will pass.

    The stimulants are the main reason why you should cycle pre-workout supplements. You need time for your adrenals to reset. A recommended dosage pattern is 12 weeks on, 4 weeks off. It typically takes me 2 weeks to completely flush caffeine from my system.

  • Nitric Oxide Side Effects: BCAAs and EAAs

    The other amino acids often found in nitric oxide supplements, such as Branched-Chain Amino Acids (BCAAs) and Essential Amino Acids (EAAs) do not have any side effects. The one exception is with ALS (Amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease) patients.

    It’s also important to note that L-Tryptophan is an essential amino acid, and if your pre-workout product has too much of it, it may make you tired.

  • Nitric Oxide Side Effects: Beta Alanine

    Beta Alanine, which is in several pre-workout supplements because of its ability to increase endurance and reduce fatigue, is shown to be safe. However, it does have the side effect of its user getting flushed, tingling skin. These “beta alanine tingles” are not completely understood, but blood toxicity studies have shown that it is still safe. Some people like the tingles, but some do not and don’t like taking products containing beta alanine. Not everyone gets the tingles. Either way, it is a kind of side effect that you should be aware of when thinking about nitric oxide side effects.

  • Nitric Oxide Side Effects: Fillers – Processed Carbohydrates and Magnesium

    USPLabs Jack3d - Our Featured Nitric Oxide Product

    USPLabs Jack3d - No Nonsense!

    If your pre-workout supplement contains maltodextrin or sugar, it’s important to note that you may be getting an undesired side effect from these substances – body fat! Carbohydrates, especially these high-glycemic carbs, lead to an insulin spike, which then leads to fat storage. This is a counterproductive side effect for anyone who is working out, and that is why 4 of the 5 recommended products on this site are zero carb products.

    Many nitric oxide supplements also contain minerals such as magnesium, which may yield a few problems that you would call “nitric oxide side effects”, although those sides would be blamed on the magnesium itself (and the company who put so much magnesium in it!) – not the arginine and pump supplements. A common side effect of magnesium is that it loosens stools and can cause diarrhea. If you are sensitive to magnesium, you will want to opt for a pre-workout supplement such as Jack3d that does not contain any.

  • Nitric Oxide Side Effects: Too Many Nitrates is Not a Good Thing

    Some of the products here, such as Cellucor NO3 Chrome and C4 Extreme contain nitrates. These products are great alone, but if you’re going to STACK them, you need to follow the directions extremely closely. You should not ingest more than 5g of total nitrates. Otherwise, your blood pressure can drop too far, opening up to a host of other things.

    The NO3 Chrome / C4 Extreme Stack, for instance, would be a max of 3 capsules of NO3 with 1 scoop of C4 Extreme.

Consuming more than the recommended dosages of these supplements will increase the severity and likelihood of these side effects. Most of the reported cases of side effects of using nitric oxide supplements are due to the intake of these supplements for extended periods. However, the nitric oxide supplement side effects either disappeared or became manageable after stopping the intake.

One last thing to consider is that when you cycle off of your pre-workout supplement, you should not take ANY other stimulants. Give your body time to reset! Unfortunately, you must deal with a few days of withdrawal when you cycle off, and that means a bit of headaches and lethargy, so grab some ibuprofen and hang in there. Not everyone gets the “caffeine hangover” though.

Sleeping issues are also common. The only way to solve this issue is to adjust the supplementation to a minimum of six hours before the bed time.

Most of the people feel that the benefits of nitric oxide outweigh the nitric oxide side effects. In short, use our recommended products wisely and you should have good success.

    I have taken Mesomorph and everytime I have had a difficult time urinating afterwards for several hours (1 to 2 days). I tried a very low dose and still had the same effect. I thought it was me, so I asked another friend that was using the same product and he had the same effect. However, his problem went away, but mine has not. What can I do. Please e-mail me. Thank you.

    • Admin 15. Jul, 2011 at 7:29 pm #

      You should probably stop taking it and try another product. My guess is it’s either the icariin (Horny Goat Weed extract – great for libido but might mess you up down there) or the 1,3 dimethylamylamine (a vasoconstrictor that might be shrinking veins down there). And drink more water!!

  2. Anthony 18. Jul, 2011 at 9:22 am #

    I have been taking nitric oxide but I was taking too much and now I’m having abdominal pain and I feel like throwing ip alot… I can’t eat anything or drink?? Why would this be???

    • Admin 18. Jul, 2011 at 10:23 am #

      “Taking nitric oxide” makes absolutely no sense (kind of like how “nitric oxide side effects” even makes no sense). What product were you taking? How much? Have you cycled off? Did you contact the manufacturer? Massive amounts of arginine can cause gastrointestinal issues. See a doctor if things don’t improve in a day or two.

  3. Daniel 19. Aug, 2011 at 9:00 pm #

    Im 17 and I was wondering if these nitric oxide products are safe for my age. And if they are safe could you list a few of the products that are zero carbs because I dont want to add fat to my body when taking it.

    • Admin 20. Aug, 2011 at 10:31 am #

      What I would do is go through our new Best Pre-Workout Supplement “flow chart” and see what is recommended. The route I would take would be Stimulants –> No 1,3 Dimethylamylamine –> Low Carb… then choose from there.

      To answer your question, most supplement companies will say that you need to be 18+, but for the majority of these products, you will be fine. Stimulants and amino acids (the majority of the ingredients) are natural and safe. The only products to stay away from are ones that mess with hormone levels, and none listed on the link above have that. Stay away from ingredients like icariin and DAA (D-Aspartic Acid – only a couple pre-workouts have it anyway).

      Also drop feedback on that since we just wrote it after writing the nitric oxide side effects page. We’ll make that page look better soon enough, but you should be able to flow through.

      • Daniel 21. Aug, 2011 at 12:25 am #

        Aright thanks the flow chart helped me out alot, ive been working out for 3 months and the only supplement ive been using is Amplified Wheybolic Extreme 60 but that doesnt get me pumped up like i thought it would. i read the ingredients on it and dint see 1,3 Dimethylamylamine listed so i dont know about amp.. after looking at the flow chart i wanted to get Jack3d or Cellucor C4 Extreme but i dont know what one to choose what would you recomend?

        • Admin 21. Aug, 2011 at 8:38 am #

          Whey Protein is great to use post-workout and in between meals (and possibly first thing in the morning if you’re not gonna get food in too soon), but yes, it won’t give you a “workout pump”. In the long run, it’ll help you build your muscles so that you continue to grow though!

          Anyway, Jack3d and C4 Extreme are both freakin awesome products. You can’t go wrong, they’re both extremely high rated.

          Personally, since you’re 17… I’d stay away from 1,3 dimeth and go with C4 due to what’s mentioned in the nitric oxide side effects article above, but 1000 people could argue that Jack3d gets high ratings for a reason!

          • Daniel 21. Aug, 2011 at 6:13 pm #

            Ok so what if I take C4 and then after weights and all that stuff I continue to take amp. Do you think that would be a bad mixture?

          • Admin 22. Aug, 2011 at 8:24 am #

            Yeah, in general. The overall diet is most important, but as far as the supplementation goes, this is just a good pre and post workout combo.

  4. Daniel 22. Aug, 2011 at 6:44 pm #

    Ok thanks man helped out alot. hopfully I wont die after a take this stuff haha.. nice page upgrade btw

  5. Andrew 28. Aug, 2011 at 5:53 pm #

    Hey i have a quick question. I am 14 5’7 and a half and weight 135. I play football and weight lift alot. I have been taking Whey protein alot and it has helped alot to. So today i decided to buy some of this NOS from the brand Body Fortress and it seems ok. Am i ok to take this stuff at my age and will it help?

    • Admin 30. Aug, 2011 at 9:26 am #

      OK, it seems that we’re getting a lot of people under 18 on this page, so we’ll have to update the page with more information for you.

      First off, at ANY age, you should seek advice of a licensed medical professional before adding supplements. That goes without saying.
      Second, NO supplement manufacturer is going to tell you to use their product at ages under 18. They can’t legally do it… it doesn’t really have to do with any nitric oxide side effects though.

      Now, that said, arginine / l-arginine based supplements are some of the SAFEST supplements you can take at any age. They are simply naturally-occurring amino acids. Whey Protein, creatine, fish oil, multivitamins, and non-essential amino acids like arginine are safe.

      At your age, you don’t want anything that will mess with hormone levels. Arginine will not do this, nor will NOS – which is just AAKG. So, in general, you should be fine, but again, seek a professional opinion.

      “Will it help?” – We believe so, and that’s why we built this site. When you take those AAKG pills, you will get all of the benefits that extra nitric oxide production helps with – improved pump, increased strength (temporarily), nutrient delivery, etc.

      Will it make you a stud on the football field? Not alone. But supplements on top of a crappy diet will just “make your pee expensive”. Your diet is ALWAYS king. Playing football, you should be getting at least 150g of protein every day (a couple shakes will help you hit and exceed your number), plenty of healthy, NATURAL fats (coconut, nuts, avocado, eggs – the whole thing, beef, salmon, chicken, etc), and a great mix of natural carbs including tons of vegetables. For bulking carbs, we like brown rice, yams / sweet potato, and oats… we stay away from processed corn always and wheat usually (some whole wheat is good, but the white stuff is garbage). Eat up!

      • Andrew 03. Sep, 2011 at 10:41 am #

        Thanks for the insight. What i take is a Mix of Creatine, Neuro Energy Blend, Nitric Blend, and Vasosurge Blend all in one bottle it said. At my age i have to eat right and good because of my diabetes (Type One had scence 7) so it really isn’t a choice to eat good food. Alot of people on my feild take some extra stuff before lifting and it really seems to help them. But one issue i noticed with this proudouct was that when tooken, i seemed to sweat alot more heavily when in activity ( Running, not lifting) and i had a slight faster heart beat. But then again it did feel like i could run more. Is this completley normal while taking this?

        • Admin 06. Sep, 2011 at 11:50 am #

          Stimulants will certainly increase sweating (they are thermogenic and make you put off heat / burn more energy) as well as raise the resting heart rate and slightly bring up blood pressure. This is normal for stimulants and I wouldn’t be concerned, but if you are, speak to your doctor and consider lowering your dosage. Keep an eye on your heart rate and if it’s ever out of the safe zone for your age range, back off on the stims!!!

          • Andrew 16. Sep, 2011 at 7:06 pm #

            Thanks man. You should really add the Body Fortress Proudouct to your list it is a great proudouct.

    I have just received delivery of Lean Muscle X that I ordered as it was advertised as a “Free Trial” What do you guys know of this brand and is it ok to take if you are on medication for high blood pressure?
    I am 58 yrs old, and just want a bit of extra help to increase my fitness and lose some weight from around my middle!
    Many Thanks for your time guys!


    • Admin 06. Oct, 2011 at 11:25 am #


      You need to speak with your doctor. Mixing these products with blood pressure meds may help, but it may also not help as you’re mixing far too many compounds that lower blood pressure. For instance, if this product has nitrates in it, you DEFINITELY do NOT want to take it.

      That said, Lean Muscle X looks “suspicious” at best. What this is is an affiliate marketing thing – someone got paid a major commission when you signed up for that free trial. Now there’s a good chance you will be rebilled month after month on your credit card until you cancel. Now there’s absolutely nothing wrong with this — IF the price is right.

      The problem I have is that I don’t see any prices and I don’t even see any ingredients or a label. Googling around, it looks like it MIGHT have these ingredients:
      “L-Arginine, L-Glutamine, L-Citrulline, L-Carnitine, Acai Berry, Green Tea, Creatine Alpha Keto Glutarate, Di-Creatine Malate, Creatine Citrate, Zinc and Beta Alanine.”

      If that’s true, then that’s not a horrible ingredient set and shouldn’t pose any nitric oxide side effects. But L-Arginine + whatever blood pressure meds may be a bad idea – L-Arginine’s NO effect lowers blood pressure through vasodilation (widening the veins). If you’re already on strong medication, this might not be a good idea. So PLEASE speak with your doctor.

      As for anyone else reading this about Lean Muscle X… if you want an NO pill, go with NO3 Chrome or Yok3d instead. But note that these DO have nitrates and MUST NOT be taken with blood pressure medication or erectile dysfunction meds. The best pill without nitrates is Nitrix.

      And finally, if you want to shed fat, these pills won’t do much of that – they WILL help you work out harder though. It’s all about diet. I’d look into the Paleo Diet, which is actually more of a lifestyle and is absolutely amazing but “different” (yet complete common sense to those of us who are on it), although tough for the baby boomer generation to swallow since it goes against basically everything you’ve learned the past 40 years.

  7. Antonios 17. Oct, 2011 at 8:40 am #

    Hi. I have recently been thinking about taking a pre-workout supplement..However Are N.O2 supplements such as superpump jak3d no xplode and Dymatize xpand bad for you? Like in general with overall health and can they cause problems with your body down the road?…Is their any way these products can cause harm to your body in any way?..Thanks

  8. Curious 12. Jan, 2012 at 3:37 pm #


    My question is, why don’t you mention icariin in your breakdown of possible side effects in your article?


    • Admin 16. Jan, 2012 at 11:47 am #

      Yeah, it’s not mentioned because icariin isn’t actually in that many pre workouts. Which nitric oxide supplement are you looking at specifically? However, there’s a good listing of studies here at Horny Goat Weed Side Effects. TONS of studies that you can google for in that link.

  9. Brian 24. Jan, 2012 at 2:01 pm #

    I’m interested in taking a nitic oxide supplement, but have a question regarding its safety with individuals with the eye disease Keratoconus. Recent data has suggested that nitric oxide (and other free radicals) are suspected culprits in the progression of Keratoconus; the body has difficulty removing free radicals from the eyes causing thinning of the corneas. Do you have any insight on whether or not supplementing with nitric oxide would increase nitric oxide levels in the eyes? I apprcaite any advice you may have.

    • Admin 26. Jan, 2012 at 11:08 am #

      Good question, I haven’t seen anything about that. You’re of course in the area where you need to see your doctor.

      That said, I would assume that more nitric oxide in the blood = more nitric oxide gas to the blood vessels EVERYWHERE, and could help. I doubt you’d notice anything though, nobody really ever mentions eyes when taking these products. We’ll do some research and update this comment, but I don’t know if the research is that granular.

  10. Nikki 25. Jan, 2012 at 11:09 am #

    I was wondering if you had any recommendations on your products for women. It seems that they are all geared to males. I just need to get over my last little hump. I am 5’3 and now weigh 127 (i have lost 42# over the last year by watching my nutritional intake and exercising). Any suggestions?

    • Admin 26. Jan, 2012 at 11:06 am #

      That’s actually a great question. I’d go for the carb-free products that are geared towards energy and a little bit of pump, not the other way around. Recommendations include Jack3d (tons of women use this for lifting and cardio) and White Flood.

      Besides some of the testosterone-supporting products like Bullrush, however, you’ll be fine with any zero carb product. They’re just marketed towards men, because, well… men buy them more. But you will LOVE Jack3d or White Flood.

      Oh, if you want to completely stay away from creatine, White Flood is my vote. But Jack3d’s creatine shouldn’t stop you – you won’t get “huge” from it and it’ll give you a little boost.

  11. Steve 29. Jan, 2012 at 12:18 pm #

    I took creatine for awhile, so i wanted to find something that didn’t have any or in smaller amounts, I also wanted something without caffeine. The person at GNC recommended Force Factor. I hear Nitric Oxide has side effects such as getting light headed, headaches and vomiting. I am 5’6 160 lbs. I know everyone is different, but how well do you think Force Factor will work for me? Do you have any tips/comments that could help avoid those side effects?


    • Admin 29. Jan, 2012 at 9:51 pm #

      The take on Force Factor is that it will work, but is FAR too expensive compared to basically everything on this site. We’re fans of NO3 Chrome, which is stronger and a better deal. However, follow the dosing — smaller people have a smaller dosage required from it. You won’t need as much as a 225lb guy. NO3 is cool because they give you that dosing on the bottle.

      But yes, if using too much of these supplements, you will get a slightly lower blood pressure (especially the stimulant-free ones), which could make you feel lightheaded. That’s why you stick to the dosing and start light.

  12. Michael 03. Feb, 2012 at 3:27 am #

    APS plasmagen nitrate? Good or bad? And dosage amounts cause its quite vague says take 6-10 capsules

    • Admin 06. Feb, 2012 at 10:06 pm #

      Let’s see, this contains PLASMAFUSE PROPRIETARY MATRIX 750mg – Beta alanine, Citruline malate 2:1, Caffeine, Theobromine.

      Basic stuff, but all four of those ingredients work in cool ways. The nitric oxide pumps you would get from that really depend on how well you respond to citrulline malate, since that’s the only vasodilator of the bunch.

  13. Paul 06. Feb, 2012 at 7:25 pm #

    Hey, I’m 23, 6’0 and 170lbs and I’m starting a pre-season workout for college soccer for next fall. I also generally want to look better and get stronger. I have read a few articles from this site, and other sources as well, and im generaly looking for a good pre and post work out suppliment rutine. I have a good diet and cook most of my meals. I’ve been lifting and running for 2 weeks now and I’ve only been using amplified wheybolic extreme 60 after my workouts. Now I just read this article and im deffinatley planning on adding an NO regiment. But im just looking for other products that would help me out in addition to what I’m already taking.

    • Admin 06. Feb, 2012 at 10:07 pm #

      Check out the diet plan on the right side of this site. It has some great insights. For soccer… I’d go with Jack3d or White Flood. You need more energy + endurance than “pumps”.

  14. Ruben 09. Feb, 2012 at 10:21 pm #

    I want to start off by thanking you for being so informative. I am very interested in taking NO, for a number of reasons, mainly for the energy gain. I am 24 years of age, and weight 195lbs. What would you recommend I buy NO2 (black or red) or NO3 chrome?

    • Admin 14. Feb, 2012 at 5:22 pm #

      Can’t go wrong with a free trial to try NO3 in the first place. You’ll need a pretty good dosage at your weight (it’s the same dosage as I use as I’m your weight), but they tell you exactly what to use per bodyweight. I really appreciate that since many others don’t give you that barometer by different weight classes.

  15. Matt 11. Feb, 2012 at 12:55 pm #

    I was wondering if cycling between multiple products is a bad thing to do? I have a good 5 types of preworkout, and will typically use different ones each different workout depending on the day. I have been lifting for a good 6 or so years, and I am 5’9″ at around 155-160 lbs. I started using preworkouts maybe a year ago, and I have become interested in trying many types! The ones I use for now are in order of preference: Razor8, N.O. Venom, Assault, C4, and 1MR. Each one seems to differ my pump feeling, but hey I guess I am just curious as to what your opinion is about using many preworkouts? And I lift 3-4 times a week typically.
    Thanks man

    • Admin 14. Feb, 2012 at 5:20 pm #

      I cycle them all the time, as I have many sent to me via this site and others. It’s fine. The important thing is that you occasionally get away from ALL stims for a few weeks (or more), and that you also stay away from any product giving you an adverse reaction of any kind.

      Also note that if you buy, say, 5 different pre workouts and rotate through.. some of them might get powder clumping and such from humidity worse than others. You can still use it, but it might seem that the ones that clump up “go bad”

  16. Ron 16. Feb, 2012 at 5:45 am #

    I am 45 years old 5’10 130lbs never took any supplements in my life, whay would you recommend me the safest supplement.
    I do very light workout usually out in 20 minutes.
    Do you think Force Factor is good for me?

    • Admin 21. Feb, 2012 at 8:42 pm #

      Force Factor will slightly “work” for some pumps, but is far too expensive and ineffective compared to NO3. What are your goals, and what are you looking for? If you want energy, go with something that has stimulants but no DMAA. Such examples would be White Flood or Cellucor C4. See our Best Pre Workout Supplement flowchart for some ideas!

  17. Jo 28. Feb, 2012 at 1:14 pm #

    I tried NO for a week. It seemed to cause a shrinkage down there . Plus a decrease in desire to engage in sexual activity. When I stopped I returned to normal size and desire after three days. Any explanation? I like the product. I worked with my muscle gain. However the listed side effects caused concern. What do u suggest should be done to avoid it? Or do you have any other recommendations?

    • Admin 03. Mar, 2012 at 3:25 am #

      Well what product???? It’s totally unfair to just say “NO” without qualifying the product. Those that have tons of stimulants can definitely have a “vasoconstrictor” effect. The stim-free pump and performance products are completely the opposite. I think you had this issue because you couldn’t handle one (or more) of the stims in a product. Please let us know which one to confirm, because it was most likely an ‘energy’ supplement instead of a true nitric oxide supplement.

  18. Michael 07. Mar, 2012 at 12:00 pm #

    I’m 19 years old, 5’8″ and 115 lbs. I workout 3 days a week. i want to put on some serious muscle as fast as possible. What supplements do you recommend?


    • Admin 08. Mar, 2012 at 10:53 am #

      Read the free diet book linked on the right sidebar of the page. It’s not just about supplements – it’s about REAL FOOD and TRAINING. Thankfully, the book mentions all three.

      I’ve blown through a few strength plateaus with Marc’s plan there, and have never been so lean while over 190lbs (6’0 here). Never realized how much I like YAMS, which I think are giving me better NO pumps too.

      Anyway, regarding the supps, check out the MTS Whey mentioned in the book, and the healthy fats too – the most underestimated part. I love the MCT oil now. Choose any pre workout you want (Muscle Pharm Assault seems like a good pick for you if you are cool with maltodextrin on your bulk), but those are more for “performance” and a bit less for muscle building. They give you more intense workouts though, which helps, but you need that food, protein, clean carbs, and healthy fats to really build.

  19. Adrian 12. Mar, 2012 at 8:57 pm #

    Hi, I’m 17 years old and I’m 5’11”-6’00” and weigh around 155. My sport is soccer and I play as goalkeeper so it’s important for me to be explosive while remaining agile and as light as possible. I’ve been working out for almost two years, aiming for the lean, but built body. I tried going at it without protein but ultimately decided to use whey protein- which has helped a lot.I was wondering if adding NO to my work out will help me reach my goal. I bought Body Fortress whey protein and NOS, will this make me bulk up too much? Should I stay away from carbs? and I’m waiting to hit a growth spurt(My dad and big brother are 6’2″) should I stay away from certain workouts, or should I just cut it altogether to be able to reach my maximum height? I work out 4-6 days a week for 2-3 hours.

      Honestly, stop overthinking it and eat real food. The diet and workout plan linked above is PERFECT for you.

      Avoid Carbs?!?!! No way! Just avoid crappy PROCESSED carbs. Sweet potatoes and yams are your best friends, followed by regular potatoes, followed oats and brown rice. Anything based from corn is completely devoid of nutrients and will kill your liver.

      At your age, you need quality saturated fats too – this is GREAT for testosterone production and will get that growth spurt an edge. I recommend the fitness book linked above for this too, but quality saturated fats come from coconut oil, MCT oil, organic butter/ghee (preferably from grass-fed cows), and grass-fed beef. Higher quality food is well worth it.

      2-3 hour workouts – you need calories. At your age, you can practically eat anything, but seriously, eat natural and eat right and you’ll pack it on in due time.

    Hi, I’m 18 years old, 6’0 and weigh a dismal 140-145 pounds. I have weight training at my school and have a gym membership. I’ve been working out every other day for about a month and a half. I take Whey Protein after work outs. I’ve had increases in the amount of weight I can lift, but I have not been able to gain any weight. I eat eat eat until I can’t eat anymore. I saw an ad for NO. I’m Looking for supplements that will make me gain some weight and maximize my workout. But I’m fearful of side effects…what are some good safe starter supplements that could help me.

      “Eat eat eat” … What are you eating? Post your diet. It’s not all about calories — the community knows that we’re beyond that “science” now. Real whole foods are king – as much as you can afford – more so than any supplement. As an honest supplement “sales guy” it’s my duty to inform you of this.

      As mentioned a ton of times here, please please download the e-book linked on the right side of the page. A bit of quality meat, eggs, veggies, yams, and GOOD fats like MCTs will go a long way for you.

      Also, weight isn’t the most important thing – if you’re getting stronger, you’re possibly simultaneously building muscle and dropping fat at once – keep at it.

      These NO supplements aren’t going to make you “gain weight” as much as the ads say. They’re gonna make you PERFORM better, which can in turn help you gain weight through shreddin up your muscles a bit mroe during your workouts. But that’s all for nothing if you don’t crush quality food. I can pump you full of pills and powders all day long, but if you aren’t obliterating sweet potatoes, oats, leafy veggies, eggs, chicken, fish, and beef, you’re not going to move.

      But with regards to the side effects… it depends on what you’re taking, as mentioned in the post. What are you looking at? For dirty bulking, I’m a fan of MusclePharm Assault.

      Last note: Work on changing the attitude. Nobody likes the word “dismal”. You weigh an ASPIRING 145lbs!! :)

    I am a 36 year old man that has just recently started working out after being dormant for years. I am trying to drop some serious weight so I can have a much healthier life. I have change my eating habits and adopted a diet which promotes weight loss. I currently weigh 425# and am lifting 4 days a week and getting in some cardio at least 5 days a week. I was considering taking nitric oxide to help support my my high rep light weight workouts. I was advised also to start taking protein supplements but was worried that it might cause me to gain more weight thus being counter productive. Any Feed back would be greatly appreciated.

      1. Stop worrying about your weight, and start worrying about your health and image. You need healthy sources of protein to build lean muscle, and you need to build lean muscle to get healthy. You will burn fat while you do this, so don’t worry, but you need protein. Weight loss is NOT the ultimate goal!!! It is just one little marker in the sea of markers – and your body image and health are more important than a number.

      2. Protein is safe, end of story. Get a quality whey protein like MTS Whey, but it’s still all about food. Real, whole, food and real leafy colorful veggies. Not crap from a box.

      3. Nitric oxide supps are fine, but your workout plan should involve more than just high rep, light weights. Eventually, you need to work up to some heavy days. You need to do slow cardio, but you also must do HIIT cardio!

      In general, check out the diet book we’re talking about here. It will go over everything, including all of the workouts you’re likely not hitting, and all of the healthy fats you’re likely skipping out of fear, which is holding you back.

        Thank you for your feed back. I will download the book & obtain a protien & no supplement. The only reason why I’m focused on my weight is because that is that is the one thing my Dr. Is looking @ right now. I am loking to improve my current quality of life. As for my health issue is my weight all my vitals are fine including cholesterol & blood sugar.

    i am taking endurance vitapak program is it safe and what is the side effects ?

    • Admin 26. Mar, 2012 at 11:16 am #

      So you’re basically taking four things here:
      Mega Men® Sport – The multivitamin. Should be good to go.
      Energy Enhancer N.O. – This advanced nitric oxide product provides 1.5g of micronized arginine… this is basically a small dosage. It would take about 10x this to get into any gas or bloating, so you’re fine. But also not the best pumps (NO3 Chrome’s dosage is stronger, for instance). All good though regarding the side effects.
      Thermo Igniter 12X – Caffeine Anhydrous, CapsimaxTM Capsicum Fruit Extract, Bioperine® Black Pepper Extract. Safe stuff, assuming you can handle the caffeine. This is where you’d feel any sides. We all experience caffeine a touch differently.
      Yohimbe 451 – Features 451mg of pure standardized yohimbe bark extract. This stuff is also where you can see some sides. Yohimbine overdoses are NOT GOOD AT ALL. But 451mg is an awesome dose – Yohimbine simply rocks for fat burning.

      Basically, don’t mix this stuff with other stimulants, especially other Yohimbine-based supps, and don’t go over the recommended dosage and you’ll be fine.

      NEVER too old, ALWAYS have hope!!! It’s all about diet. I know guys that are in their 60s and can run circles around me due to incredible diet. Check out the diet stuff linked in the other comments on this page. More than ever, you need tons of greens and less grains. Whey protein, especially post workout, rules for everyone. There’s also far better and cheaper stuff than Force Factor. Basically anything mentioned on this site, for the most part…. good luck!!!

    I am a type 2 diabetic and i workout daily at a local gym.
    My trainer has suggested me to start taking a preworkout supplement but i am not sure which one would be safer for diabetics. Can you please suggest.

    • Admin 18. Apr, 2012 at 6:10 pm #

      You really should see a doctor or general practitioner before mixing supplements and your prescription meds.

      But more importantly, it’s all about diet and training. You should talk to Marc Lobliner, who wrote Fat Loss Factor. He’s gotten many people who are COMMITTED to his process completely off of meds through strict diet, training, and lots and lots of greens. Check out the book and contact him, I’m sure he’d love to help.

      Talk to your doctor and always compare brands with lowest sugar content per serving.
