Tren turns me into a sexual freak. Dick is hard 24/7..
It's probably prolactin/e2 related. Maybe try some caber or prami as others have stated. It's hard for me to comprehend how some guys can have issues with libido and erections on tren. So that's the only thing I can think of.
Warning with the caber/prami. Be prepared to fuck, then 10 seconds later be ready to go again. Your lady will be like wtf.
And start low on the dose and work your way up. I've taken too much and spent a couple hours hugging the toilet all while having an erection...
Weird ass drugs. And trying to sleep on Prami is like you feel tired, but just lay there and toss and turn all night then wake up in zombie mode(for me anyway).
Because there's no other aas like it, and for me it's addicting as fuck. The only reason I stay away is because of the neurotransmitter effect it may be having. My dopamine is sky high while on it then when I come off tren I get all depressed for a couple weeks. I have no idea wtf it is doing to my brain.
I'm sure I'll end up back on it at some point though.
