I have been on my first test e cycle (500mg/week) for about 6 weeks now. I’m 37 yrs old, with 15 yrs training experience. So around week 6, I decided to add some Winstrol (40mg a day) to reduce the bloat and increase strength without size. I do parkour so I wanted to improve my jumps etc. My training ability after adding Winstrol has been tremendous. I feel unstoppable (with a few joint pains here and there)! My libido however has gone down considerably, it took me by surprise! My question is, could this be due to the Winstrol? Or maybe it’s just my estrogen that is too high?
