Pretty much legit Bayer stuff, afaik my source is legit Proviron from greece. Yesterday I had really great sex again with a chick btw, I loved it, was rock hard all through, had a good sensation and came within a good time. The anabolic effects- if any- are scarce, but I love the effects on mood and libido this stuff has. I will make an apt with my endocrinologist soon, to see if I can negotiate with him if he can follow me through with this with monthly blood tests and checkups .
