Ipamorelin

How it works

Mimics ghrelin, the hunger hormone, at the pituitary to trigger one pulse of growth hormone. Sold as the one that spares cortisol.

What it's made of

5 amino acids (Aib-His-D-2Nal-D-Phe-Lys-NH2), two of which do not exist in nature. Novo Nordisk presented it in 1998, by removing two pieces from GHRP-1. It mimics ghrelin.

What it's for

Prescribed for

Nothing.

Sold as

Raises your growth hormone without spiking cortisol: muscle, recovery and sleep.
