Hi all, my simple question is: does adding T4 medications stop natural production just like in trt? Is this a concern? Does it cause atrophy?Is ok to stop it? Is any kind of pct like process for it? Thanks
Thanks for your reply. Really appreciate it. My thyroid values are : tsh- 1.11 t3 - 3.4 t4 - 1.1. I believe my values are in the low optimal range. I would like to push it to optimal values. Should I ask for t4 medications or it would be better option just supplementation? For the t4 option should I start by minimal dose 0.25 mcg levothyroxine for example? Sorry for questioning but doctors here are really bad and don't even have an opinion.
Please post the ranges associated with the test results you've provided. Without them we're unable to offer you any thoughts. How old are you? Are you taking any medications/supplements?
