ALright, this may sound like a really stupid question and i have been a part of these forums for a while now. I am currently looking into homebrewing my own Tren. I am in the learning process....ive searched through TONS of forums and i appoligize for asking this, but what exactly does BA and BB stand for? Ive seen they are most used in %'s. Ive searched around before posting this thread, so please dont drop the whole..."dude do your research" thing, because Ive been looking. Thanks guys.
