That is more of a skin disorder not related to hormones. Its almost as if he had a bad reaction to whatever he put on topically rather than what he injected intra-muscularly.He clearly irritated it further somehow and did not seek treatment early on. My guess its an allergic reaction to something topical.
Looks like a bad infection from dirty underground gear.
Was he fucking drinking sulfuric acid or what??
He drank too much Cell Tech.
