I just spend the money and order the Pharm grade shit. I realize there are some great sources out there for UG AI's and Serms. I just like to know exactly what I am putting in my body due to the fact I am very Gyno prone. Plus I hate using the liquid shit with the stuff floating around in it, how can I possibly be getting an accurate dosage...? Just my opinion brothers, I'm not gambling in this department anymore LOL.
