I don't plan on using any of these three substances anytime soon but I was wondering if anyone has tested using melinotan II for deca (or tren) dick? From what I've read melinotan's libido enhancing effects act on the brain vs something like viagra which just works on penile physiology (that's why melintan works for women as well as men). I think I could argue both sides theoretically and I don't really want to do this experiment on myself. Has anybody ever run these at the same time? What happened? Just curious.
