Damn those are some high ass dosages of T3 but I might go that high some day if I need too. As for the challenge sounds good to me. I saw a medical journal about people that were misdiagnosed with thyroid problems and given T3/T4 for years when they shouldn't have been on it. When they found the problem they made them stop the medicine and all off their thyroids were back to normal within 3 weeks I believe. I have taken it and been fine, IMO it is a scare that people that haven't used it keep pushing and will never die for that reason! BTW, I do see it having a problem in people that have some type of pre-existing thyroid problem.
