Aromasin doesn't need to be 25mg/ day. It should generally start around 12.5/ day
Also, I get bad acne, especially during my pct. platinum labz sells "acne annihilator" and it seems to work pretty well. Contains salicylicacid along with an exfoliant. Tanning helps also, but nothing seems to eliminate it completely :/
If you're acne prone it's just something you have to live with knowing AAS may very well being it out again.
Just drink lots of water and be sure to stay clean. Not much else you can do
