Ipamorelin

Growth Hormone Releasing Peptide

Ipamorelin is a selective growth hormone secretagogue that stimulates the release of growth hormone by mimicking ghrelin activity at the pituitary. It is studied for support of recovery, lean mass preservation, sleep quality, and healthy body composition.

How Ipamorelin Works

Selective GH Release

Activates ghrelin receptors to trigger pulsatile growth hormone release from the pituitary.

Limited Off-Target Effects

Designed to have minimal stimulation of cortisol and prolactin compared with less selective peptides.

Supports Recovery

May support lean mass retention, tissue recovery, sleep quality, and overall resilience.

Protocol Tips

Often administered subcutaneously
Frequently used in the evening or around recovery windows
Consistency matters for cumulative results
Can be paired with resistance training and adequate protein intake
Track body composition, recovery, and sleep

Cycle Guidance

Typical research cycle length: 8–16 weeks
Reassess goals and response before continuation
Breaks between cycles may be considered
Often used as part of a broader body-composition or recovery strategy
