yeah, but that's a given. like oxygen...just part of the landscape.
actually, what people do not realize is that FOOD is the number one bb supplement. try and gain mass without it.
but product wise, for me, its creatine...hands down. its the only supplement, besides protein, to have been proven to actually put new muscle mass on you. it doesn't just assist, it actually does it.
Aside from test, BCAA would be first choice with creatine a close second....proteins and recovery supps I can always substitute food...same with omegas and fish oils.
I'd have to say that if whole food is not considered a supplement then I would choose a stimulant over creatine. Workout intensity is a far greater stimulus for growth.
