It helps immensely with stamina, added extra reps from day one for me. I know when I take it I bust it in the gym, you can over work like crazy.. Hard to fatigue at all... If you have a long workout routine, whether it's good or not, and I do, it definitely helps you make it through start to finish strongly. Of course it's muscle tech and it is high priced but I really have to give vapor a thumbs up... I've tried MRI black powder, and Noxplode. They're not even in the same league.. Only thing I can say is never buy it in the store catch it online at a discount.. I really like to hit it up when I'm just draggin ass. WHich I know is my fault because I overwork. Whatever is in that stuff puts me in the zone, even if it's just in my head... ANd I have tried other similar supps without the same results.. SO All I can say hrdgain, is that it works for me. It give me satmina when I need an extra push. I'd be open to any cheaper versions.. I've tried citruline malate,beta alanine, and caffeine. Just not quite the same.
