How to Use Cytomel While Using T4?

Hi all.

Question that I haven’t been able to find an answer to.

How would I dose Cytomel for fat loss when using T4 for thyroid replacement?

I had a thyroidectomy a long time ago and use Synthroid as my replacement. When taking Cytomel would I continue using it throughout?

Proposed cycle: 250 mg Cypionate weekly for 12 weeks, Cytomel 50-75 mcg daily for 8 weeks.

Stats: 5’8.5, 233, between 10-12% bf.

Thanks very much everyone.

Do you know blood levels of free T4, free T3 and reverse T3? May want to check TSH as well, though it should be bottomed out.
