OK, so just to let you guys know. I have been pulsing epistane for 9 weeks now. When I pulsed superdrol last year it ended up killing my cardio. This year, pulsing epistane, my cardio has actually improved. Ok, so I dont run much. lol. Last time I ran was at Christmas. Now almost 6 months later I ran 7miles 15 minutes faster than at Christmas. Zero cardio in between times, and afterwards i fealt like I could just continue to go on forever. I know a lot of people are always interested in steroids that dont negatively affect their cardio. So here one is, and it actually appears to improve my cardio. I dont know if anyone has addressed this yet, but here you guys have it. Anyone else have similar affects?
