GHRP-2 vs Hexarelin
| Attribute | GHRP-2 Growth Hormone Releasing Peptide 2 | Hexarelin Hexapeptide GH secretagogue |
|---|---|---|
| Category | Muscle Growth & Performance | Muscle Growth & Performance |
| Best known for | Reliable GH-release research | Potent GH release and cardioprotection research |
| In plain English | Stronger GH pulse than ipamorelin but weaker than hexarelin, with mild appetite stimulation and small cortisol/prolactin bumps. | The strongest GH-pulse peptide of the classic GHRPs — but also the one most likely to raise prolactin and cortisol, and develop tolerance. |
| How it works | Activates the GHSR receptor to stimulate GH release. | Strongly activates GHSR and also exerts CD36-mediated cardioprotective effects. |
| Researchers study | GH secretion, appetite, and IGF-1 elevation. | GH secretion, cardiac tissue protection, and post-MI recovery. |
| Internet discussion | Used by researchers who want appetite stimulation alongside GH research. | Discussed for short, intense research protocols due to tolerance. |
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.
Hexarelin
Potent GH release and cardioprotection research
The strongest GH-pulse peptide of the classic GHRPs — but also the one most likely to raise prolactin and cortisol, and develop tolerance.
Strongly activates GHSR and also exerts CD36-mediated cardioprotective effects.
GH secretion, cardiac tissue protection, and post-MI recovery.
Discussed for short, intense research protocols due to tolerance.
Hexarelin is the most potent classic GHRP with notable cardioprotective research signals.
