Tried it years ago from a Mexican source. It just felt like a weak clomid to me. It's a mild anti e & a poor choice for PCT. IMO, 40mg nolvadex beats clomid, cycolfenil, tribestan etc for PCT. Not only hormonally, but it also doesn't make you depressed like clomid does.
On a side note, I've heard from a very reliable source that the original Hot Stuff supplement worked so well because it had cyclofenil as one of the 'secret' ingredients. The original batch really worked well for a supp, although it really wasn't a natural supp.
