Great Preworkout Pump And Volume

Posted by iHerb Customer on Sep 22, 2016 | Verified Purchase

I like NIOX. In itself, it produces a great 'feel' and muscle pump. Strength and stamina a tad better than without. I can highly recommend a stack of NIOX and N-Vein (also Nutrex) - Best non-stimulant preworkout I have tried. Can add Agmatine to the stack and get even better pump, torque and stamina. If I use Nutrex products preworkout, I like a stack of NIOX, N-Vein + a serving of a BCAA product (Xtend, Atomic7 etc) and some creatine. It works great!! I am not a big fan of too much caffeine and this stack has none.

Thanks for your feedback!

When I first started the pills I would be laughing for a while at the begining. Then I'd have a constant hard for about an hour. Other wise there are other products out there that work better.

Thanks for your feedback!
