Yes, I know. The Dienedione products were once marketed as a "tren" pro hormone although they really weren't.
I'm just curious if Dienedione (estra-4,9-diene-3,17-dione) would show up as a trenbolone metabolite on a urine steroid screen. I know they are structurally similar so would it potentially cause a false positive for trenbolone or its metabolites?
