I had been planning to try clen for the first time ever after my current ox cycle is over. Then I heard about how it "hardens your heart", which has supposedly been proven in numerous studies. What exactly does that mean? Im a boxer, so would my cardio be temporarily, or worse, permanently hindered? Im not exactly "safety first" (done DNP, Tren, etc, etc.) but I dont need no stinking "hard heart". Any suggestions/warnings/opinions on the safety of clen MUCH appreciated. peace
