It's an anti-estrogen, so if you are on something that easily coverts to estrogen, then it will help keep you dry and possibly prevent gyno. If you are really worried about gyno, I'd have some nolva or torm (actual SERMs) on hand just in case of a flair up.
Btw, a SERM is a Selective Estrogen Receptor Modulator while the ATD in Inhibit-E is an anti-estrogen. If you have questions about the difference, shoot me a PM. :cheers:
