I have lots of friends who have acne and have been prescribed accutane. All I heard from them is that it's a very hepatotoxic drug. Most of them have cholesterol and liver problems after 3-6 months of treatment. I also had acne for over 2 years but I've never been prescribed accutane. I eventually found a doctor who would perform laser treatments for acne and went through 7 BBL (blue light) and 4 Thermoscan treatments. They are much less invasive and also seemed to work for me. All I can tell you is that acne has no cure. It will last until you are ~30, you can't stop it but you can control it.
PS: Working out raises your testosterone levels, this is not caused by bodybuilding supplements. It is a normal consequence of working out but will be very severe if you decide to take steroids.
