anabolic diet supplementation

I am currently in the midst of a cutting cycle using the old “anabolic diet”. In addition, I am using 50 mcg of cynomel daily in an attempt to accelerate my fat loss. Do any of you have any experience with supplements that I should be using during this six week period? I am taking a multi vitamin, fish oil, extra C, and vitamin E. My research tells me that Carnitine would be a worthwhile addition. I started out at 6’1", 221 pounds, and 12 percent b.f. I am looking to lean out considerably, and stay above 200. I know that catabolism is a major concern when using cynomel. Any suggestions?
