IMHO, I like Proviron, always run it twice a day @25mg (while on test). I purchased it in bulk a while back, never had any signs of gyno while on it, except for my most recent cycle that I started without Proviron! About a month into my cycle I started to get some discomfort under one of my nips when I would ly down on that side!

I could palpatate a small lump under my nip about the size of a pencil erasure, never painful just discomfort!

I have a medical physican friend who is a good mentor, however I still come here for information and advice, he said that it was just some breast tissue forming, did a ultra sound in his office and much to our surprise, the lump under my nip didn't show up, so a tumor was ruled out, and after some anti bod's, the lump went away in 2 weeks! So we came down to the conclusion that Proviron works great for me in blocking E build up, if you have the extra $$$'s I don't think you could go wrong taking it, never heard any post saying that it hurt their gains!

Just my 2cents!
