Sup guys , I went to the dermatoligist (sp?) a few days ago about my acne.. My acne isn't real bad but just wanted to see if there were some things i could do for it to clear up. Anyways my Dermatoligist gave me a drug called doroxycylene (I believe that's how you spell it.) I dont have it right in front of me and i'm at work right now so i cant double check the spelling. I guess it's a common prescription for acne. My question is; Does doroxycyclene have estrogen to lower my testosterone levels? If so, is it enough to effect my muscle growth? I'd rather live with a little acne or try clearing up other ways than have a pill I take twice daily slow my progress... Please help. Thanks in advance.
