What's up guys? Hey i wanted to know if ANYONE has used or thought of using this compound in the place of an AI? the compound is 4-hydroxyandrostenedione and converts to 4- hydroxytestosterone. The company claims the it is a "Formestane is a suicidal aromatase inhibitor" and a 5-alpha reductase inhibitor. I think i will run it with my test e/d bol cycle. Let me know what you think...
