We talk about the rear delt being an obvious sign of GH usage. We talk about it as a 3D thing. It is said that a bodybuilders drug regimen can be identified by the mutation and protuberance (like that word) of the rear deltoid.
Arnold had shit for rear delts. There are side-poses where you see nothing. He worked them every day because of this "weakness" ~ yet he worked his calves in excess and posed in water because of this "weakness" (and they actually grew?) ~ then there is the rumour of implants.
I have seen only pro bodybuilders in my gym who have the crazy shelf-like delts and humongous traps. I already know what they are on. I'm not guessing.
My question is this: If a bodybuilder (genetics aside) only grows "3D" mutated rear heads on the posterior delt, and we attribute this to GH and a few other assorted drugs, will he lose these rear delts when he stops that particular dope?
Arnolds calves seemed to have hung on for years after he backed off of his training regime, but now they look like they are gone.
What gives? Opinions?
Here are some pics. Of course I photoshopped them, for the example, analogy, whatever.
No rear delts to speak of. Not like the Pros today. Always looked funky especially with the huge chest. Maybe not back then, but they do now that we have seen such huge delts today (please don't include Nasser in this)

Photochopped with rear delts, more traps and a smaller chest:

Typical delts on today's Pro competitors:
