t3 is an essential part of my contest prep toolkit. 50mcg/day for the last 8 weeks with a proper taper down over 2 weeks at the end. it keeps my metabolism from adapting to the caloric deficit which is crucial when youre getting very lean. the difference between using and not using t3 in prep is significant - without it the last few pounds of fat just wont budge. thyroid recovered fully within 3-4 weeks after proper taper
