For me, I love Proviron, it takes about a week to get in your system good, right now I'm on the Bayer proviron and have been back on it for 6 days, just started feeling better/a little extra frisky in the evening. 50mg a day is a good dose but with the Bayer I can get away with 25. In a few days I'll bump my dose to 50 when I know that the wife and I are going to have some fun

My first 5 weeks on this cycle I didn't take any Aromasin or Caber only Proviron & Masteron and my estro was fine......now I
won't try that again but I've never had
problems with estro. Please Don't try it because gyno isn't
fun . Also, Proviron makes me feel better. ....could just be me but I feel excellent once my system becomes saturated. Hope this helps !

Yeah, any other brands besides Bayer I have to take 75-100mg. PSL , Vermodje and Balkan are the others I've had .
