Bout to start a 10 week cycle of Andropen 275. Have Nolva and Clomid for PCT. Been working out for 6 years. I'm 42, 220 lbs 6'4". Goal is to just add some decent size rather than my normal basketball/athletic build. From what I've been reading for the last year, I'm going to make some decent gains. However, I am a bit concerned about the estrogen build-up during the cycle. What would you recommend for battling this? EstroBlocker, Nolvadex XT, etc? Can you take these with Andropen?? I looked into Arimidex, but that is very hard to come by and expensive. However, I want something strong so I can feel confident no man-boobs arise! Any input is welcomed.
