stretchmarks, particularly around the shoulders and underarms is a definite hallmark of steroids use
it happens from the muscles growing at a rate faster then the skin is prepared to stretch.....this typically does not happen to nattys because naturals dont just all-of-a-sudden put on 20 lbs. or 40lbs. of lean mass like hormonized people do
BALONEY!!!
You can put on that much weight in a matter of months (even it's not all lean mass) and STILL get stretch marks, especially when you're a teenager. I know that first hand.
I don't get it with all these weaklings, who seem to not be able to brush their teeth without needing a cycle of something. It's sad.
