I wouldn't advise using acutane on cycle, the possible side effects could mess with your gains and intensity on cycle. eg joint aches, depression, weakness, dry skin. I guess you could always stop it if side are unbearable but ive also seen a lot of people complain about reoccurring back pain, and development of athratis and other disease related to bones and shit even after taking the drug. There many people who get minimal or no side effects. This is just info i have found through my research i thought you might be interested.
