Some test would be good or some sort of anabolic/androgenic! The clen would be fine on it's own because it interacts with the beta-2 receptors and causes fat metabolism; however, T-3 causes an overall increase in basil metabolic rate and burns everything...fat and muscle!
Depending on what t3 dosage you're running, you want some kind of AAS to retain muscle. So I have to ask, why are you using t3 anyway, and at what dosage?
