My buddy recently stopped shooting his delts and now claims to stick to just quads and glutes and has virtually no issues anymore with acne developing on his chest, back, shoulders and even face. He previously would have some pretty serious breakouts to the point he couldn't even wear tank tops anymore (not for fear of looking like a douchebag...(other thread) but from the embarrassing look of acne ridden skin). Anyone else ever observe this and have any ideas as to why this may be? Also for you guys that suffer with bad acne issues possibly give the upper torso shots a rest and see if it helps. I thought it would be a systemic effect but I have seen the results with my own eyes.
