Formestane hands down. I've tried both and Arimistane (if we're talking about the active ingredient in many OTC AI's, for example PES Erase) doesn't come close to formestane as an on-cycle AI. Formestane keeps estrogen in check even when I'm running heavily aromatising compounds like testosterone and dianabol. I also managed to get rid of old gyno with it.
I gotta agree - for those purposes it is great. I've used Finaflex Revolution PCT several times and I'm planning to use it during my next PCT too as I still have one bottle of it in my stash. But as on-cycle AI it doesn't stand a chance against Formeron or other transdermal formestane products that really inhibit the aromatase enzyme.I have always had great success with Arimistane (as in Revolution PCT) especially when paired with DAA. Either in PCT or as a natty test boosting run. I have had never had any adverse reactions, such as loss of libido, joint problems, etc.

Arimistane is better during PCT because it doesn't suppress natural testosterone production or hinder the recovery of it. Formestane converts to 4-OHT (4-hydroxytestosterone) and is suppressive so it really shouldn't be used as a part of PCT protocol.
Testosterone and masteron are also great for libido boosting but they are also suppressive.form is suppressive? from the reviews, everyone said it was great in libido boosting
Yes it can be suppressive at high doses. OP how were you going to use it? As a natty run or pct?
200mg of Formeron was enough for me to get rid of gyno and 75mg of Formeron daily is a good dose for me to keep estrogen under control when running low dose of injectable testosterone.Was gonna go for a natty run or possibly with some DAA and last 2 weeks hit it with clen. Would 100mg be enough form?
