Woody, yes formeron can be used as estrogen control. Ive been using it for close to a year and the results are great! Im still having some estrogen issues but mine are more because of the compounds Im using. Im come to the reality that some Dr. are still somewhat cluesless about TRT/HRT. Like you Ive found out so much by researching on boards like this. One Bro you might want to PM would be Heavyiron, hes really good at estrogen issues, helped me a ton with mine. I asked my Dr. about meds for estrogen, was referred to an Endocrinologist, asked the same question and was told they only prescribe meds for TRT/HRT and nothing for estrogen...interesting. There are also tons of stickies on the subject on the main page, hope this helps some.
