GHRP-2 vs GHRP-6
Pure GH release vs ghrelin/hunger-driving GHRP.
| Attribute | GHRP-2 Growth Hormone Releasing Peptide 2 | GHRP-6 Growth Hormone Releasing Peptide 6 |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Reliable GH-release research | Ghrelin-receptor GH release and appetite research |
| In plain English | Stronger GH pulse than ipamorelin but weaker than hexarelin, with mild appetite stimulation and small cortisol/prolactin bumps. | Same family as ipamorelin but with stronger appetite stimulation and more cross-talk (prolactin, cortisol). |
| How it works | Activates the GHSR receptor to stimulate GH release. | Activates ghrelin receptors in the pituitary and hypothalamus, triggering GH release and strong hunger signaling. |
| Researchers study | GH secretion, appetite, and IGF-1 elevation. | GH release, appetite, and cachexia models. |
| Internet discussion | Used by researchers who want appetite stimulation alongside GH research. | Discussed as the 'appetite GHRP' — often cited for hunger more than recovery. |
GHRP-2
Reliable GH-release research
Stronger GH pulse than ipamorelin but weaker than hexarelin, with mild appetite stimulation and small cortisol/prolactin bumps.
Activates the GHSR receptor to stimulate GH release.
GH secretion, appetite, and IGF-1 elevation.
Used by researchers who want appetite stimulation alongside GH research.
GHRP-2 sits between ipamorelin and hexarelin in potency and side-effect profile.
GHRP-6
Ghrelin-receptor GH release and appetite research
Same family as ipamorelin but with stronger appetite stimulation and more cross-talk (prolactin, cortisol).
Activates ghrelin receptors in the pituitary and hypothalamus, triggering GH release and strong hunger signaling.
GH release, appetite, and cachexia models.
Discussed as the 'appetite GHRP' — often cited for hunger more than recovery.
GHRP-6 is an early-generation ghrelin mimetic researched for GH release and appetite stimulation.
