Sermorelin Research Peptide

In short: Sermorelin is a synthetic growth-hormone-releasing hormone (GHRH) analogue corresponding to the first 29 amino acids of native GHRH, supplied strictly for in-vitro laboratory research and not approved for human consumption. It is a common reference compound in pituitary and GH-axis signalling studies. Research buyers should require ≥99% purity by HPLC, identity confirmation by mass spectrometry, and clear batch numbering.

What is Sermorelin?

Sermorelin is GHRH(1-29)NH2 — the first 29 amino acids of endogenous growth-hormone-releasing hormone with an amidated C-terminus. It was developed as a shorter, synthetically accessible version of the full-length 44-amino-acid GHRH molecule, and is the shortest GHRH analogue in active research use, carrying no additional structural modifications. In laboratory systems it acts at pituitary GHRH receptors on somatotroph cells. It is offered here purely as a research reference material.

What does the research investigate?

Pre-clinical studies use sermorelin to probe GHRH-receptor signalling and the dynamics of the growth-hormone axis. In vitro work with anterior-pituitary cultures has reported dose-dependent increases in intracellular cAMP signalling associated with growth-hormone release, while animal studies have examined pulsatile GH secretion and downstream changes in circulating IGF-1. Its short half-life makes it a useful tool for studying pulsatile GH dynamics and pituitary responsiveness. These findings are pre-clinical and do not establish human safety or efficacy. Always read the primary sources directly.

Purity and quality: what research buyers should check

≥99% purity by HPLC (confirm via the batch certificate of analysis, or COA)
Identity confirmed by mass spectrometry
Batch numbering for full traceability

Vexar Lab supplies Sermorelin as a pack of 10 vials, ≥99% HPLC-verified, batch-numbered, with mass-spec confirmation.

Handling and storage

Standard lyophilised-peptide practice applies. Store sealed vials at -20°C, protected from light and moisture. After reconstitution with an appropriate sterile diluent, keep refrigerated at 2–8°C and use within the period indicated by your protocol. Avoid repeated freeze–thaw cycles, which degrade peptide integrity, and allow vials to reach room temperature before opening to limit condensation.

Wholesale supply

Vexar Lab supplies research peptides in packs of 10 vials, with a £300 minimum order, bulk pricing on volume, £45 flat worldwide shipping, and optional custom labelling for resellers.

Frequently asked questions

Is Sermorelin approved for human use?

No. Sermorelin is supplied solely for in-vitro laboratory research and is not authorised by Vexar Lab for human consumption or therapeutic use.

How does Sermorelin relate to native GHRH?

It reproduces the first 29 residues of GHRH with an amidated C-terminus, the minimal fragment retaining GHRH-receptor activity in research systems.

What purity should research-grade Sermorelin meet?

Look for ≥99% by HPLC with a batch COA and mass-spec identity confirmation to ensure traceable, reproducible results.
