What is GC-1 and what does it do?

Thyroid hormone regulates the metabolism of food and controls our body’s ability to burn off fat.

GC-1 is also known as Sobetirome. This research chemical is a thyroid hormone receptor agonist. Also known as a thyromimetic, it mimics thyroid hormone without actually being a hormone. To put it in perspective, you could consider this the SARM of thyroid hormones.

GC-1 acts similar to thyroid hormones like T2 and T3 in the body. However, it doesn’t seem to cause negative side effects of thyroid meds like suppression of TSH (thyroid stimulating hormone) levels. Other studies show GC-1 to increase  metabolism and fat burning without causing tachycardia, which is a side effect  from using T3.
