Hey, I am currently on Masteron Prop, Test Cyp & EQ 3 weeks in, and I am noticing more endurance. Whenever I do something that should hurt I am REALLY less affected now. Is it because of one of those substance or is it just in my head :P
Most steroids increase red blood cell count, especially eq. More rbc= more endurance. For that reason, cyclists and endurance athletes take epo to drastically increase rbc but epo is dangerous without doctor supervision.
