I never did understand the whole AA for x amount of time then start E. My docs started me on E, AA and P immediately, might have something to do with my low base T levels though, idk.
When I started I weighed about 115-120 lbs, a few years later I was at 145 (my heaviest) and then I dropped down to 130, however my boobs and butt have mostly stayed the same in terms of fat, despite the weight loss.
So my advice is if anything try gaining weight gradually as the years go by, rather then trying to gain it in a short amount of time. I say this because fat redistribution takes years to happen fully and with a steady gain, it should redistribute to the ideal areas rather than mostly in your gut. Quick weight gain mostly goes to the tummy pouch that E creates.
