How To Treat Severe Acne Inspite Of Taking Minocycline And Testosterone Shots?

I am taking testosterone shots and developing bad acne. I have taken minocycline up to 3 times a day and it does not seem to help. My Dr. cut me down to 1 cc from 4 per month. This small dosage will not up my level to where it should be. Is there a different drug to take for the acne problem?
