i think toremifene is your best bet. no sides, while clomid did give me mild emotional sides and a slightly noticeable decrease in night vision acuity.
exemestane doesn't affect the lipid profile... might be a good addition since SOS500 has LMG (estrogenic) and SD (can cause rebound gyno)
but i don't have experience using exemestane in PCT except just recently but i ran out on like day 10...
