My girlfriend is using clen and has a prescription for T-3. She is ow using taurine because of clens effect on the liver and thyroid. My concern is how much she should use. She haas had and beat thyroid cancer but now i dont know how much she should be using. She used a very low dose of clen 20mcg for week 1 but now I am going to have her go to 40mcg then 60mcg. How much taurine should she be using and is there anything else that anyone can think of.
