I want to hear what some of my brothers opinions are on pharma grade AI's and SERM's vs. UG. So far all I have used is UG and have been plagued with some gyno. Not real bad and not noticeable to the average person. (slight puffiness of nips and I have masses under both of them). My pec's are huge anyways so it's hard to tell. Now, back to my question....If I had been using Pharma grade AI's and SERM's up to this point, would I have had a different outcome? I finally ordered some Pharma grade shit and am going to give it a go to see if it is any better than what I have already tried. What are your experiences?
