The info in this thread is OUTDATED
/EDIT
I recently figured out (on my own!) that drinking milk was a HUGE factor in my acne, causing deeper-lying annoying acne. I cut out milk completely and I have been very happy with the results. I have now noticed that whey protein may have a similar effect on my skin (although lesser than milk).
I read this from the the waisays site:
"If you MUST have supplementary protein, you should take liquid free amino acids. They are absolutely clean and you can choose the exact amino acids you need. They are easily absorbed and 100% utilized. (they just taste disgustingly and are expensive) If you want to know what amino acids in what rates you need (some supplements lack one or more of the essential ones, which makes them worthless), send me an email."
Could you please recommend some amino acids supplements I could take (and how much)? I am 5'10", 155lbs, very athletic, train 2 hours martial arts daily, and have a very high metabolism. Whey protein has helped in the past with muscle gain but if I can find a solution that does not cause acne, I would be eternally grateful to you for your advice!

Thank you in advance,
Alex
P.S. I've read the post on creatine in these forums.. but not sure what the effect of creatine is on acne... If anyone knows, let me know! I'm going to do my own experimentation on this as well.
