If you are using accutane, the main thing you want to stay away from is orals. And yes, accutane can dry your joints out and make you more prone to injury. In fact, I suffered a pretty decent set back while using accutane, so be very very careful. Now that you mention it, a little deca may be very beneficial while on the acc cycle, maybe around 300mg EW. I do have one thing for you to consider. If you are given accutane through your Dr in the US, you will be required to take part in the "I Pledge" program. Part of this program requires you to have very regular lab work done. Injectables can still throw things out of wack and may scare your dr. He may think the accutane is causing problems
