Im about to start sustanon 250 500mg per week for 10 weeks, and dbol weeks 1-4 30 mg per day. Should I run an anti estrogen and hcg as well during my cycle? I'm just very scared about losing libido and what not... Please any help would be greatly appreciated! Right now I have arimidex from ar-r for an anti estrogen. im going to run clomid and nolvadex for pct and more than likely hcg as well...
