Ipamorelin vs Tesamorelin + Ipamorelin
A side-by-side research comparison of Ipamorelin and Tesamorelin + Ipamorelin across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Ipamorelin | Tesamorelin + Ipamorelin |
|---|---|---|
| Full name | Ipamorelin (Selective GH Secretagogue) | Tesamorelin/Ipamorelin Combination |
| Category | Growth Hormone | Growth Hormone |
| Status | Research compound | Compounded combination |
| Mechanism | Selectively activates GHSR on pituitary somatotrophs. Unlike GHRP-6 and hexarelin, does not significantly activate ACTH or prolactin-releasing pathways. | Tesamorelin stimulates GH release by activating GHRH receptors on pituitary somatotrophs. Ipamorelin amplifies the pulse by acting on ghrelin/GHS receptors. Together they produce a synergistic "1+1=3" GH release while maintaining physiological pulsatility. |
| Molecular weight | 711.9 Da | Blend |
| Half-life | 2 hours | Tesamorelin: ~26 min; Ipamorelin: ~2 hours. Combined peak GH at 30-60 min post-injection. |
| Bioavailability | High (SubQ) | High (subcutaneous) |
| Typical dose | 100-300 mcg | Tesamorelin 1-2 mg + Ipamorelin 200-300 mcg |
| Frequency | 1-3x daily | Once daily (before bed) or twice daily |
| Route | Subcutaneous injection | Subcutaneous injection |
