proviron can be added to any cycle. it is very mild and safe. does not cause liver strain
binds to SHBG.
proviron in pct is debated but i would not do it. the studies people reference were biased to push its use, but didn't apply to the way we cycle steroids in bodybuilding. until someone comes to me with iron clad proof that proviron didn't suppress them off cycle i won't recommend it. (haven't seen proof yet)
