I have used both. 6 0x0 works on libido if you follow PCT instructions. I believe I started at 10 caps per night and slowly tapered out. Formestane can be suppressive if you stay on too long so I've heard. With Form, you have to taper out slowly and you can stay on for up to 8 weeks. Some people do a low dose pulse of EOD at 2 pumps per day. Just do it you'll like it. I think it's the best OTC AI/PCT out there. It's good in so many different ways that others are not. Estrogen control, improves mood, leans you out/sheds fat, increases strength, boosts Testosterone, cost effective.
