So I have heard this rumor..
Ok so.There is a friend of mine who really wants to jump in gear with a sustanon-boldone-primo cycle.(he doesn't listen for test only).one day we were talking about deca and it's traits.He said this.that deca can block the vasodilation in your ol boyz and so stop the erections.even if someone stops cycling his erections will never be the same.something like that.yes deca like tren causes the dysfuction from prolactin and progestin.But really does something like that exists? He said the same apo dianabol .I don't believe many things he says cause he listens to brainless bodybuilders who are on gear for like years.
