Premenopausal women's primary source of estrogen created by the ovaries rather than the aromatase enzyme, so all of the available aromatase inhibitors aren't going to significantly reduce your estrogen levels.

so its not enough to bother with it?

I don't think it is worth the bother.

It won't supress estrogen in women but because it is an androgen it works well as a hardening agent. You would use Nolvadex to control estrogen and proviron to help harden you up.

Use Nolvadex to block estrogen, not to control it.
