I think its more genetic some have acne in teens and some dont. If your one of those that had it in teens juice will most likely bring it back. I usually dont see juice users in 40s and up get it though. Acne sucks but I love being a superhuman so I deal with it. I do use some otc products, they help but dont completely get rid of it. You can run a course of accutane, but its dangerous and id rather just deal with a few zits than potentially harm my self. Juice if misused can be dangerous but accutane is far worse imo.
I ran a test only cycle above a gram a week and for longer than I should have(yes I realize my rookie error), anyways that cycle I broke out all over my back and chest....BAD. Nothing on the face, arms, etc, but my chest was the worse. It took about 6 weeks post cycle to clear up. Since then zero problems.
