T2 T2

A minor thyroid-hormone-related compound studied in rodents for quickly boosting metabolism without straining the heart the way full thyroid hormone can. There's very little human data on it, and it's sold mainly through research-chemical websites for weight loss without dedicated safety or effectiveness studies in people.

Also known as 3, 5-diiodo-L-thyronine
