I’m convinced the majority of sides are self-induced from reading about them on the internet and being a hypochondriac, or psyching yourself into having them.
Mood changes are one. You see it with lots of other drugs. Whiskey makes me do this, but vodka makes me do that. And people really believe that of themselves, which is simply silly.
My half-hot take is that most deca-dick is self-induced. Seems like kids touch the bottle and their dick just goes limp. I’ve ran deca at a gram for months and everything worked fine. It really wasn’t a thing you heard much about until forums started parroting what they overheard about deca-dick once in a bar.
Ok but I say all that, but, tren makes me act like a cheap knockoff of American Psycho. So there’s that too.
