The all knowing FDA does not approve of human use. You cannot have it prescribed. I have crazy high SHBG that was stealing most of my free T even on heavy handed TRT. You'll have to do your own homework to find a source that is reliable.
I've read that Proviron lowers SHBG is some and in others it had no effect. I even read that one said it increased their SHBG. So, like many things TRT or hormone related, it can vary by individual body chemistry.
