So I've been bulking since summer now and to my misfortune I got a case of pretty serious acne on my face (I'm 22-years-old). I've used whey protein, creatine, bcaa's, vitamins, fish oil as my supplements during this bulk.
What I am wondering is, has anyone had similiar cases? How did you treat it and how can I avoid this in the future? Creatine hasn't caused acne when I've used it previously, but maybe it is a mix of bcaa's, creatine and increased body mass/metabolic levels?
