I notice the same thing. When I am on, my skin is clear as ever, but afterward I break out. When I did a Deca Winstrol only cycle I had no problem with acne. The two times I did Sustanon and Omnadren I broke out horribly. So.... It sounds like you are very similar to me in our skins sensitivity to Test products.
I basically have two options. Get on accutaine and get liver damage with no zits, or do Deca, Primo, Winny, D-bol cycles and maybe include a very small amount of Test to kick them off. To tell you the truth. The Deca Winny cycle gave me more solid results than test anyway. Test just makes me a big baloon with zits.
