Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.
| Attribute | Hexarelin | Ipamorelin |
|---|---|---|
| Category | Growth Hormone Secretagogue | Growth Hormone Secretagogue |
| Evidence Rating | C — Phase I–II Clinical Trials | D — Preclinical |
| Clinical Status | Phase II completed. Development discontinued due to tolerance/desensitization concerns. | Research-only / Not approved for human use |
| Mechanism | Hexarelin binds to and activates the ghrelin/growth hormone secretagogue receptor (GHS-R1a) in the pituitary and hypothalamus through a triple mechanism: direct stimulation of pituitary somatotroph cells to release stored GH, stimulation of hypothalamic GHRH-releasing neurons, and suppression of som... | Ipamorelin (sequence: Aib-His-D-2Nal-D-Phe-Lys-NH2) selectively binds to the Growth Hormone Secretagogue Receptor (GHS-R1a) on anterior pituitary somatotroph cells, increasing cAMP and activating protein kinase A to promote pulsatile GH secretion. Its structural specificity means it fits only the GH... |
