T3 & Thyroid suppression

Does anybody know at what dosage T3 becomes suppressive? I know P22 has mentioned this before but I can’t find the post - he mentioned using a low dose for extended periods of time in contest prep.

Thanks.

Anything above 12.5 micrograms per day. Thats 1/2 a tab of cytomel.

Thanks for the reply P22 - much appreciated.
