I have acne on my shoulders and back the last few months now as well as aggression just wondering if this is normal. I dont use any aas or test boosters im all natural. Some ppl think im on gear because of this and also because ive been making alot of gains and putting on weight pretty fast. Is this normal. Im 27 went from about 165lbs to 185lbs in 4 months. There was a 1 week period I gained 7 lbs in 10 days. Any insite would be great.
