If that terrorist organization the FDA, and yes, I truly believe they are WORSE than a terrorist organization, had there way, they would probably ban everything right down to vitamin C. If it can't make them and their lobbyists money they don't want it.
Ephedra? DHEA? Andro? All, when properly dosed, cycled and taken in by a repsonsible adult, are harmless. Yet they banned the two and are trying to bad the third. Why? Money.
Yet they pimp out ADD drugs, antidepressants, cholesterol medications, which are all MUCH MUCH more harmfull then the before mentioned substances, to the american public as "safe".
There a bunch of criminals if you ask me.
