ok.. Vitex agnus castus and B-6 show an ability to lower progestin sides..
but if you really want to do a number on it, get some Cabergoline (Dostinex) from a research lab. It reaaaally works.. the only con is that it's a dopamine agonist.. so you should use low doses.. like 1mg E5D.
It's less harmful to you than Bromo... and a reminder b-6 has been shown to cause nerve damage when used at doses around 500mg for any prolonged period of time.
Also a very easy way to get rid of Progestin-penis is just to use more Test... lol..which I KNOW you're a fan of Deo.
Cabergoline's efficiency of reducing prolactin enables you to keep a boner after you cum... allowing you to keep on going.. essentially allowing you to have multiple orgasms in a single session.. I've done it.. I'm now a god because of it.
