People are sometimes confused by "lower weight, higher reps". I don't lift light, but not as heavy as a power lifter. As much weight as I can in the rep ranges I suggested. And that's primarily for size.

You should eat the same in PCT as you did while on both PH or AAS. You built new tissue and need to feed it. You may lose some water weight while on PCT depending on what you used, and that will improve your appearance. If you want to lean up, wait until after PCT and try to lose is slow to maintain the new muscle.
