I have used this product only once a day for pre-workout (3 pills 1x a day). However, the label states (Beginner 3 pills 2x a day) (Intermediate 4 pills 2x a day) (Advance 5 pills 2x a day).

I used it 30 minute prior my training, and let me tell you this is one of the best product to rash your adrenaline and makes you hyper for the first 30 minute of your training. Personally, I think this product will also suits very well for boxer or MMA fighter since it makes them very energetic for short period of time. As a result, I left heaver weight than the normal days when I am not using it.

I am not sure how effective this product is in the long run and also with continuing daily use. Some of the days, I didn’t feel any power even thought I had it before training, good sleep & with proper nutrition.
My opinion, I think this product should not be used always (daily). You should keep it as a magic pill when you feel weak and out of energy that will be the best time and most effective time to use and get the benefit out of it.

Note: I don’t think this product intention is to build muscle as much as helping you to left heavier which might result in building muscle if you ensured you’re having good nutrition to aid you in your recovery.

This is a decent nitric oxide booster, but it is not the best. I always use nitric oxide boosters for my workouts, like Animal Pump or Gakic. I found this particular product is most effective for the first 15 days, after which your body tends to adapt to its formula. Then I switch to another nitric oxide booster. I also use this product when I am taking a fat burner which has stimulants, so as to avoid taking more stimulants from other nitric oxide boosters which provide hefty doses of stimulants.

It worked immediately. Felt increased energy and focus throughout my 45minute workout. Agree with the previous value reviews ..... this stuff works great but cost is a major factor. Was stacked with BSN Syntha-6, MegaMen multivitamins, Focus Fast, and ZMA.

Good product but doesnt seem to work after a few weeks, not great value either. but for the first few times i took it my veins were popping out of my arms and my blood pressure appeared to go thru the roof. my face wud be purple and itchy, very intense rush. this is when u take 8 or 9 at once tho. gives short term burst and definatlely extra strenght for half an hour but very unsure as to actually gaining muscle with contineous use of this product

I took an entire bottle of this over the course of a few weeks late last year. My two friends, both training partners, split a second bottle of this stuff.

None of us had any results from it, whatsoever. I should note that even Nitrix, which i do NOT reccomend, was better than this.

This literally did nothing. And the pills are gigantic.

I took this stuff as a freshman in high school. It worked good for me. Even after my workout i couldnt breath. it gave a major pump to me. It used to be the best. but that was three or four years ago. But the pump was pretty good.

now im giving this review not lifting at the gym...because this product really didnt provide with an intense out this world work out like Jacked or supercharged xtreme....but now what it does do which the others dont is give you an amazing super hard mini-me(guys if you know what im talking about)...i mean wow!!!!!!...if anybody is having problems in the area...your mini-me or middle man...take this stuff...it will be up day and night....forget Viagra

i liked it alot.i got a crazy pump after i took it like it said and they really do dissolve quickly.the problem i have with it though for me at least was it only worked well the first couple of workouts.

have just started taking but have not noticed any negative side effects, pumps while i'm working out are huge!! HUGE! but within an hour they are completely gone. Not sure how long its supposed to last but i expected longer. I will continue to take this and see if pumps hold longer...

My first experience with a nitric oxide product and it seemed to do all it claims it would. From the first time popping them in my mouth, i felt it breaking down immediately. Then ofcourse I got THE pump of my life. I'm not so sure if it makes you stronger right then and there but it definitely gives you stamina to keep going and going and going. I just stopped working out cus I ran out of things to do, and I've been a personal trainer for 4 years now... The pills are actually very big and I made the mistake of trying to swallow all three at once the first time... Dont do that... I bought it at GNC on sale, plus I used my Gold Card so I got it for $37. Reasonable I would say... But lucky. Definitely recommend it with a weight gainer for those trying to really mass out. Try the Xience Extreme Weight Gainer at the same time!
