I remember reading that there was a rough formula for this.
Having started on T3 over the last couple of months I have gradually arrived at a dose which initially felt like magic! Sadly it only lasted for 2 days and although the dose is still the same (3 x 20mcg Thybon) symptoms of constipation, afternoon tiredness, and cold shivers have returned. I am not basing my dosage on test results and I’m being guided by how I feel. Please don’t all say this is wrong.
I am interested to know what my 60mcg is equivalent to in terms of T4 just out of interest.
