It'd appear that everyone is aiming to squeeze the most out of the training investment of theirs so that as a result, the supplement industry has globally become a multi-billion dollar industry.

A huge majority of the supplements available are either insidious e.g.. Ephedrine or even have very little positive aspect at all on performance e.g. orthonine, arginine.
