I just got done with my Superdrol cycle, and I'm on day 1 of my PCT. My libido was fine while on-cycle. I'm hoping that I don't see a drop during my PCT. So far nothing out of the ordinary. No noticeable testicular atrophy for me either.
Just make sure you eat a lot!! If I were you, I'd just eat until I couldn't eat any more. Don't worry about gaining fat. Just eat!!
On a side note, just because my libido was fine and I experienced no noticeable testicular atrophy, that doesn't mean you'll have the same results.
