My body goes into super-achy mode with 700mg/week of Mast Prop. Like can’t get out of bed because everything hurts so bad achy. Two days later when its largely out of my system, all good again. Not to mention, that much mast WILL ultimately cause your hairline to recede–ask me how I know–and that, too, reverses when you go off mast. I’ve settled on 20mg of Mast Prop ED. More than that, my body and my hairline freaks out. Curiously, I seem to have a greater tolerance for Tren Ace, at least physically. I can do 50mg of Tren Ace ED without any physical consequence (even my cholesterol remains low). Emotionally, I become a wrecking ball, going off on the slightest thing. So for that reason, I limit Tren Ace to 20mg ED as well. Each combined with 40mg of Test Prop. That stack–Test Prop at 40mg ED, Tren Ace at 20mg ED, and Mast Prop at 20mg ED–has proven to be just about perfect for me. And every now and then, I’ll double the Test Prop just to have a little fun. THAT makes me one horny mother!
