The effects that both of you noted are due to the excess amount of caffeine and other ‘energy sources’ in the product. It’s just a powdered energy drink, and the strength gains that people report on it are due to 3 things-
1)Caffeine and other energy stimulants
2)Creatine (big one)
3)Placebo (big one).
If someone likes the effects that they feel from a NO product, it’s easily (and more cheaply) reproduced with a caffiene source and creatine.
