GHRP-2 vs Hexarelin
A side-by-side research comparison of GHRP-2 and Hexarelin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | GHRP-2 | Hexarelin |
|---|---|---|
| Full name | Growth Hormone Releasing Peptide-2 (Pralmorelin) | Hexarelin (Examorelin) |
| Category | Growth Hormone | Growth Hormone |
| Status | Research compound | Research compound |
| Mechanism | Potent GHSR-1a agonist stimulating GH release and appetite. Also mildly stimulates ACTH/cortisol release. | Potent GHSR-1a agonist producing maximal pituitary GH output. Additionally binds cardiac CD36, providing cardioprotection through anti-apoptotic mechanisms independent of GH. |
| Molecular weight | 818 Da | 887 Da |
| Half-life | 1-2 hours | 1-2 hours |
| Bioavailability | High (SubQ) | High (SubQ) |
| Typical dose | 100-300 mcg | 100-200 mcg |
| Frequency | 2-3x daily | 2-3x daily |
| Route | Subcutaneous | Subcutaneous |
