Im taking a 8 week cycle stacking Tren (19 Norandrosta-4,9 diene-3,17 dione) and Phera (17 a-Methyl-etioallocholan-2-ene-17b-ol). I keep getting mixed opinions on my PCT. I have this product which is 4-hydroxyandrostendione, Androstentrione, and I was going to take for 4 weeks after the tren/phera along with a test booster. I would like to know if this is sufficient, what recommendations do you guys have for proper PCT. I definetly don't want to get gyno. Please leave comments or suggestions, thanks
