GHRP-2
Also known as: Pralmorelin · KP-102
A growth-hormone-releasing peptide (GHRP) that stimulates the pituitary to release a pulse of the body’s own growth hormone, and is also known for a notable effect on appetite via the ghrelin pathway.

Proposed mechanisms / pathways
What is GHRP-2?
GHRP-2, also known as pralmorelin, is a growth-hormone-releasing peptide (GHRP) — a small synthetic peptide that signals the pituitary gland to release a pulse of your own growth hormone rather than introducing growth hormone directly. It belongs to the same family as GHRP-6 and Ipamorelin, and is generally described as a potent GH releaser that also carries a meaningful effect on appetite.
How it is thought to work
GHRP-2 is thought to act on the ghrelin receptor (GHS-R1a), mimicking the body’s natural "hunger hormone" signaling to prompt a pulsatile burst of growth hormone. Because it engages the ghrelin pathway, it is also reported to stimulate appetite — though typically less than GHRP-6. It is frequently paired with a GHRH analog like CJC-1295, which is thought to complement this mechanism.
Educational only — not medical advice
GHRP-2 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 GHRP-2 in LynkDose
GH secretagogues are timing-sensitive and their effects build slowly, so consistent logging matters. Record each dose and time of day in LynkDose, and because GHRP-2 often involves more than one injection daily, the log helps you keep cadence consistent. Then let objective metrics — sleep, HRV, and weight from Apple Health — accumulate, since the relationship only becomes visible as a multi-week trend.
Commonly discussed for
- Supporting the body’s natural growth-hormone pulse
- Appetite and the ghrelin pathway
- Body-composition and recovery goals over longer timeframes
Often stacked: Often combined with a GHRH analog such as CJC-1295 to pair a GH-releasing peptide with a complementary mechanism.
How to track GHRP-2 in LynkDose
GHRP-2 is timing-sensitive and is often dosed more than once a day, so log each dose and time. Because it can noticeably affect appetite, many also note hunger alongside sleep and recovery trends.
