Ipamorelin

Also known as: Selective GH secretagogue

A selective ghrelin-receptor agonist studied for growth-hormone pulses, recovery, sleep and body composition.

What it is

Plain-English overview

Ipamorelin is a small peptide that activates the growth-hormone secretagogue receptor. It is valued in research for a cleaner selectivity profile than some older GH secretagogues.

Mechanism

How it is thought to work

By mimicking ghrelin signalling at GHS-R, it prompts a pulse of the body's own growth hormone. It is often studied alongside GHRH analogues that strengthen the same pulse window.

Research interest areas

Lean-body-composition models
Recovery and training stress
Sleep and wellbeing markers

Evidence

What the research suggests

Studies show reliable GH release, but long-term human outcome data remains limited. Its reputation comes from selectivity and the way it works with natural rhythms.
