I’ve upped my Proviron to 25Mg 2xED for a while now, and it does a great job of keeping my free test in the 700-800 range. Mast doesn’t seem to do quite as good a job at that for me, but does make me look a little better. Mast gets me pretty achy after continuous use though. That Proviron is oral and not a liver-killer does make it convenient. Like Poppy, the ED pinning does get old. At least I have it down to only one pin per day. Used to be two, and that was horrific.
