Ipamorelin

Very early research

The research is at the earliest stage – mostly cells in a lab dish. It is far too early to say much.

Also called NNC 26-0161 / Growth hormone secretagogue

A lab-made peptide studied for raising the body's own growth hormone. Research stalled early and there is no approved use.

The basics

What is it?
A lab-made peptide that nudges the body to release its own growth hormone.
What do we know?
In early tests it does raise growth hormone in the blood, without much effect on other hormones.
What do we still not know?
Whether raising growth hormone this way changes anything people care about. Development was dropped years ago.

Can a doctor prescribe this?

Not FDA approved and not on the 503A bulks list, so there is no legal compounding pathway.
