| Evidence Tier | Research Compound |
|---|---|
| Category | Muscle Growth & Performance |
| Class | Synthetic hexapeptide GH secretagogue (GHRP); potent ghrelin mimetic with cardiac-specific effects |
| Molecular Target | GHS-R1a (ghrelin receptor); also acts on CD36 scavenger receptor on cardiomyocytes for GH-independent cardioprotection |
| Sequence | His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 |
| Molecular Weight | ~887 Da |
| CAS | 140703-51-1 |
| Parent | Methylated GHRP-6 analog |
| Mechanism | It binds tightly to the ghrelin receptor in the brain and ignores the body's natural "stop" signals, resulting in an unnaturally large surge of growth hormone release. |
| Studied For | GH secretagogue research, Cardiac protection / cardioprotection, Cytoprotection, IGF-1 elevation, Body composition / lean mass, Anti-aging via GH axis, Fat loss via GH, Heart failure models, Ischemia reperfusion research, Pituitary GH function, GHS-R independent cardiac effects, Muscle growth research, Bone density via GH, Recovery and repair, Ghrelin axis signaling, growth hormone secretagogue, muscle growth, heart health, cardiac protection, ischemia |
| Administration Route | Injection Only |
| Form | lyophilized |
| Diluent | bacteriostatic or sterile water |
| Storage Temperature | cold, dark |
| Light Sensitive | Yes |
| Freeze / Thaw | avoid |
| Reconstituted Shelf Life | 28 Days |
| Handling Notes | Most potent classic hexapeptide GHRP; most prone to desensitization. |
| Regulatory | Not FDA-approved; research chemical; WADA S2. |
