Be very, very careul with T3. It must be titrated down gradually. I hit a peak of 100 mcg and on Wednesday drop it down to 75mcg. I keep it there until I finish 2 days of post contest food binging. Then, 50 mcg for 3 days, then 25 3 days then 12.5.
If you stop using abruptly, your hair will fall out among other bad things.
