for those following the saga, i have "the worst back acne my dermatologist has ever seen" as a result of trt and a test+deca cycle, and have been battling it for the last 9 months. at my office visit today, i saw a sub dermatologist who is a fellow fitness nut, and she mentioned that whey is a strong contributor to acne. i've done a bit of research and found a bunch of bro science reports, and one real science report:

Whey protein precipitating moderate to severe acne flares in 5 teen... - PubMed - NCBI

i just placed an order for paleo protein powder (egg+beef) for my shakes and will see how such affects my acne. i'm also going on accutane today, so the experiment won't be clean. but dammit, i gotta clean up my back!
