I think it depends on the person. Some people don't convert hardly at all and don't have gyno issues. Theirs quite a few older guys here that don't run an ai at all. If your not gyno prone, your conversion factor is low and you've ran enough cycles to know your body I don't think theirs anything wrong with good generic. If you're not sure or its your first cycle then yeah I'd go real pharmaceutical.Why would you order anything but Pharma PCT gear? There are threads here with no bad reviews that sell PCT
