"Many anabolic steroids aromatize (convert to estrogen via the aromatase enzyme), and this is responsible for many of the unwanted side effects found with anabolic steroid use (acne, gynocomastia, water-retention, etc..)."

taken directly from steroid profiles section.

i started getting acne on my shoulders where my traps are and a little bit on my back around week 8 or 9. i still have it but its clearing up...tanning helps and clean shirts and sleeping with a shirt on and acne anhilator. i also use these pads used to clean your face it has saylic acid in it, i use that on my shoulders. basically acne is my main concern here...not gyno prone at least from the 1 cycle i have done.

diet is in check now and doing 30 mins of LIT cardio a day or EOD...thanks for the advice dude.
