Ipamorelin
Also known as: Growth-hormone secretagogue · Ghrelin-receptor agonist
A selective growth-hormone secretagogue that prompts the pituitary to release a pulse of the body’s own growth hormone, known for being relatively clean and selective compared with older peptides in its class.

Proposed mechanisms / pathways
What is Ipamorelin?
Ipamorelin is a growth-hormone secretagogue — a peptide that signals the pituitary gland to release a pulse of your own growth hormone, rather than introducing growth hormone directly. It is known within its class for being relatively selective, meaning it tends to trigger GH release with less effect on other hormones like cortisol or prolactin compared with older peptides such as GHRP-6.
How it is thought to work
Ipamorelin acts on the ghrelin receptor (GHS-R1a), mimicking the body’s natural "hunger hormone" signaling to prompt a GH pulse. Because the release is pulsatile — a short burst rather than a constant elevation — it is often described as working with the body’s natural rhythm. This is also why it is frequently paired with a GHRH analog like CJC-1295, which complements the mechanism.
Educational only — not medical advice
Ipamorelin is a research peptide and is not an approved medication for general human use. Nothing here is a recommendation, dose, or medical claim. Consult a qualified healthcare provider and follow the laws in your area.
Tracking an Ipamorelin protocol
GH secretagogues are timing-sensitive, and their effects (sleep, recovery, body composition) build slowly. Log the dose and time of day, then let objective metrics — sleep duration, HRV, and weight from Apple Health — accumulate. The relationship only becomes visible as a multi-week trend, which is exactly what a tracker is for.
Commonly discussed for
- Supporting the body’s natural growth-hormone pulse
- Sleep quality and recovery
- Body-composition goals over longer timeframes
Often stacked: Very commonly combined with CJC-1295 to pair a GHRH analog with a GH-releasing peptide.
How to track Ipamorelin in LynkDose
Timing matters — many log Ipamorelin at night. Track the dose and time, then watch sleep and recovery metrics from your wearable trend over weeks.
