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