Trial of T3

I’ve been taking Levothyroxine 100 mcg for quite a few years, levels of which are taken by GP annually but only TSH and T4 and are always reported as ‘in range ‘. I’ve not had any energy for a long time so did some testing myself with medichecks

My results from 16/01/23 are

CPR HS 1.13 ( 0-5)

Ferritin 62.9 ug/L ( 13-150)

Folate serum 24.73 ug/L ( > 3.89)

Vit B12 active >150 (37.5-150)

Vit D 167 (50-200)

TSH 1.64 (0.27-4.2)

Free T3 3.58 ( 3.1-6.8)

Tree Thyroxine 17.2 (12-22)

Thyroglobulin antibodies 285 iu/mL (<115)

Thyroid peroxidase 14 (<34)

Thyroglobulin is a bit high but what I would really like to do is to increase T3 .

My GP isn’t very receptive and is unlikely to offer much advice. At this point I would like to source some T3 independently to see if my symptoms improve. If so then I can hopefully get an Endocrinologist here to supervise. Does this seem a reasonable way forward to you and can anyone help on where to source T3? . I am a dentist so understand the medicine and drug protocol.

By way of comparison I had a basic thyroid test in November

TSH. 0.18 ( 0.27-4.2)

FreeT3 3.9 (3.1-6.8)

T4. 19.5. (12-22)

Does this suggest I have a conversion issue?

Many thanks
