I am a 33 yr old female 5'7 150. I look good, but have body fat! I am on 2 iu a day! You should go no more then that esp. cause you are fit!!!!!! I am also on Anavar (var) 10 mgs, Clen 9stopped because of brutal side effects. was thinking about adding methanddrolosone! Maybe pick up T3s as I have a very bad thyroid and i am on heavy t4s! Why on earth would you want to take t4? if you dont have thyroid issues! T3 converts into t4! I cant take t3 alone as it messes up my blood test for t4, i felt weird, etc. Also on lipozene, metabolup,
