Well, I use orals like d-bol and drol mainly to kick start my cycles of slower acting injectables. I'll stay on them from 4 to 6 weeks allowing the slower acting injectables to kick in. I won't mess with a-50 or d-bol if I'm using stuff like suspension, prop, or fina, because they go to work fast. As far as keepable gains go, a-50 and d-bol are classic "easy come/easy go" drugs. Gains come quick and dramatically and leave the same way. That's why the slow acting/long lasting injectables are my primary drugs and oral androgens play only a supporting role, if any. I run them for short periods of time because they can be harsh. Like the fellows said, d-bol is easier to control, anti-Es will keep the gyno away, and most people feel great on d-bol. A-50, to my knowledge, causes gyno via the progesterone route and is harder to prevent. A-50 is the only thing that made my nipples sore. High dose deca and fina never caused a problem, though they supposedly cause gyno through the same mechanism as a-50, but a-50 gives me a problem. Also, like many people, I feel like I'm coming down with the flu or something when I'm on a-50. I'll say this though, only tren make me as strong as a-50. For strength, it's probably the best oral I've ever taken. D-bol is no slouch though.
