What Is Sermorelin?
Sermorelin is a synthetic peptide analog of growth hormone-releasing hormone (GHRH). In laboratory settings, Sermorelin is used to investigate:
• Peptide–receptor interactions and signaling mechanisms
• Pituitary hormone signaling models in vitro or ex vivo
• Peptide stability, structure, and analytical characterization
• Endocrine pathway studies under controlled experimental conditions
• Laboratory-based peptide biology and mechanistic research
All applications are strictly non-clinical and intended for scientific study only.

Compound identity and specification
Identity data for Sermorelin, published so the material can be checked against an independent record rather than taken on trust. The formula, mass and registry number below are verified against PubChem and can be looked up directly.
| Compound | Sermorelin |
|---|---|
| Sequence | GRF(1-29) amide, the first 29 residues of human growth-hormone-releasing factor with a C-terminal amide |
| Molecular formula | C149H246N44O42S |
| Molecular mass | 3357.9 g/mol |
| CAS registry number | 86168-78-7 |
| PubChem | CID 16132413 |
| Vial content | 5 mg |
| Physical form | Lyophilised powder in a sealed vial |
| Analysis | Third-party HPLC; the result for this product is published on this page |
| Supplied for | Laboratory research use only |
Analytical note — Sermorelin. At 29 residues this is long enough that deletion and truncation by-products from incomplete coupling sit close to the target mass. A mass difference of one residue against a 3,358 g/mol parent is a small relative shift, so mass resolution matters more here than on a short peptide.
Identity references The molecular formula, molecular mass and CAS registry number above are taken from the PubChem record linked in the table, not from a supplier datasheet, so every figure can be checked against an independent source in one click. Sequences are given as reported in the peptide literature, in the one-letter or three-letter convention as appropriate, with any non-standard residue named in full. Where a compound exists in more than one form — a free peptide and a metal complex, a fragment and its parent protein, a modified and an unmodified analog — the form supplied is the one identified here, and the mass on the certificate of analysis is what distinguishes it.
