Yeah, it comes down to many factors. Size, type of muscle fibers, training regime. If you are training as a powerlifter, you want explosive power, which denotes fewer repetitions. If you are a bodybuilder, you are trying to build mass. Totally different kind of training.

In terms of the size, weight argument... gotta take strongmen into account as well!

In terms of this thread, I would say losing some strength during PCT would be normal. Though it always comes back to that old chesnut... everybody is different .
