What is Ipamorelin?

A selective growth hormone secretagogue (GHS) considered one of the milder GH-releasing peptides. Popular in anti-aging clinics and often paired with CJC-1295. Not FDA approved.

How it works

Selectively binds to ghrelin receptors (GHS-R) in the pituitary gland to stimulate growth hormone release in a pulsatile pattern that mimics natural secretion. Unlike other GHS peptides, it does not significantly raise cortisol or prolactin levels.

What marketers claim

▸builds lean muscle effortlessly
▸burns fat without diet changes
▸completely safe with no side effects
▸as effective as HGH injections

What evidence supports

✓clinical studies confirm selective GH release with minimal cortisol or prolactin elevation
✓shown to increase bone mineral content in animal models
✓considered one of the better-tolerated GH secretagogues in limited human studies

Best for

those exploring GH optimization under medical supervision
