GHRP-2 vs Tesamorelin
A side-by-side research comparison of GHRP-2 and Tesamorelin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | GHRP-2 | Tesamorelin |
|---|---|---|
| Full name | Growth Hormone Releasing Peptide-2 (Pralmorelin) | Tesamorelin Acetate (Egrifta) |
| Category | Growth Hormone | Growth Hormone |
| Status | Research compound | FDA Approved |
| Mechanism | Potent GHSR-1a agonist stimulating GH release and appetite. Also mildly stimulates ACTH/cortisol release. | Binds pituitary GHRH receptors with enhanced affinity via hexenoic acid modification. Effective at mobilizing visceral fat via GH-mediated lipolysis. |
| Molecular weight | 818 Da | 5,136 Da |
| Half-life | 1-2 hours | 26-38 minutes |
| Bioavailability | High (SubQ) | High (SubQ) |
| Typical dose | 100-300 mcg | 2 mg |
| Frequency | 2-3x daily | Once daily |
| Route | Subcutaneous | Subcutaneous injection |
