PRO ACNE
I used to wonder that myself cuz everytime I went "on"I would get it on my upper back and shoulders, one time it was spreading down my triceps. I tried a lot of showers, benzoyl peroxide, etc. then one day while on my (lost count) I think 10th cycle I noticed I wasn't getting it anymore and now I can go on and off and no difference, although when I come off, if I use clomid sometimes I still get a few on my back. I think my body just adjusted to it. I'm thinking the same thing happens to the pros. Also I noticed that staying on longer seemed to help. I like to go on for 4 months, off for 2 months. 2 cycles a year one bulking one cutting.
