I lost pubic hair when I overdosed. It works. I'm using steroids, and I currently have a supraphysiolgical level of testosterone, and large waves of DHT moving around my body regularly. RU is more effective than Propecia.
Acne is usually only a problem when the hormone levels are fluctuating. I do have some right now, but nothing which bothers me. It seems like I get a lot of acne in the face, when estrogen raises. I've not used any treatment for acne. An outbreak usually subside within a week.
