My buds that use the sauce are really regimented when it comes to trianing and diet - so there goes your theory.
I am not saying that all QV products are shit - I just think QV EQ might not be worth the money. Its your cash spend it how you want.
Quality empirical data!
The only way to tell if gear is good is to see if it tests out to the label claims. Going by a friend's results or even your own interpretations is misleading since there are far too many factors involved to isolate. Even if you think you are doing everthing the same, you are not going to always get the same results. If a compound tests out to be legitimate, and dosed correctly, that is what matters. I have mostly seen good things from QV tests.
As for being underfilled, one also has to remember that the needle tip in the syringe also contains more substance. This means that you could be overfilling each dose, leading to there being less at the end.
