Overview

Researchers in the 1990s found that the tail end of growth hormone seemed to carry some of its fat-burning effect. Most published work used related fragments, like AOD-9604, in rats and mice. There are no solid human trials of fragment 176-191 itself.

How it works

In animal studies, the growth hormone tail increased fat breakdown and fat burning without raising blood sugar or IGF-1 the way full growth hormone does.

How long does HGH Fragment 176-191 stay in the body?

Not established in people.

What it's studied for

Fat breakdown in obese rodents
