Lets start off by saying i've tried many so far (vapor/noxplode/superpump250,etc). (I will say this about the overall suppliments that it will work for some more then others base on how each of us are different)To sum things up its a good suppliment in case of creatine/NO combo preworkout energy booster. Its not as a jolt of energy like others, more spread out energy. Some might get stomach irritation (casual bathroom run, or runs). You should take a try and see if it works for you (majority it will work and nicely) if not, you can try all the other suppliments (for me my stomach agrees more with superpump250). I recommend both and there's others out there too. And as always...do research to know what your putting in your mouth.
