Questions about Sermorelin

How much published research is there on Sermorelin?

The research library's PubMed search for Sermorelin returned 365 records on 5 October 2026, 9 of them reviews. The library lists 5 studies chosen for what they measured. ClinicalTrials.gov lists 27 registered studies naming Sermorelin (checked 5 October 2026).

Is Sermorelin an approved medicine?

No centrally authorised medicine containing Sermorelin is listed in the EMA medicines database (checked 5 October 2026), and the research material we supply is not a medicine. It is supplied for in-vitro laboratory research only, not for human or veterinary use.

How was the parent peptide of sermorelin discovered?

A 44-residue growth hormone-releasing peptide was isolated from a human pancreatic tumour and its amino acid sequence determined, with full activity of the synthetic replicate (PMID 6812220). Sermorelin corresponds to the first 29 residues.

How does Sermorelin differ from Tesamorelin?

Sermorelin is the first 29 residues of human growth hormone-releasing hormone, amidated. Tesamorelin is the full 44-residue sequence carrying a trans-3-hexenoyl group on Tyr1. Both act on the GHRH receptor.

How does Sermorelin differ from CJC-1295 no DAC?

CJC-1295 without DAC and sermorelin are both 29-residue amidated analogues of the N-terminal fragment of growth hormone-releasing hormone. They differ at four positions.

How is the identity of Sermorelin confirmed on a certificate?

A research-grade certificate of analysis typically reports identity by mass spectrometry and purity by HPLC. The mass result is read against the average molecular weight of 3357.9 Da listed on this page. The research library's guide to reading a certificate explains each field.

Is this product for human use?

No. Peptency products are supplied for in-vitro research only. Not for human or veterinary use, not for diagnosis or therapy.

Where can I find shipping information?

Current shipping rates and delivery information are on the Shipping & payment page, and the rates that apply to your order are shown at checkout.

What is Sermorelin?

Sermorelin is GRF(1-29)-NH2, the first 29 residues of human growth hormone-releasing hormone, which was isolated as a 44-residue peptide from a human pancreatic tumour in 1982. Published work covers the isolation and sequence, receptor cloning and reviews. We supply Sermorelin as a lyophilized vial for in-vitro laboratory research only.

What are the chemical identifiers of Sermorelin?

Sermorelin has the molecular formula C149H246N44O42S, an average molecular weight of 3357.9 Da and CAS number 86168-78-7.

Chemistry checked against PubChem (CID 16132413), 5 October 2026; full chemistry record in the research library.

What does published research on Sermorelin cover?

A PubMed search for Sermorelin returned 365 records on 5 October 2026, 9 of them reviews. Our research library lists 5 of these studies, chosen for what they measured.

  • A 44-residue growth hormone-releasing peptide was isolated from a human pancreatic tumour and its amino acid sequence determined, with full activity of the synthetic replicate. (Guillemin et al., Science, 1982; PMID 6812220; Rivier et al., Nature, 1982; PMID 6292724)
  • The pituitary receptor for growth hormone-releasing hormone was cloned and expressed, with ligand binding and cyclic AMP production measured in transfected cells. (Mayo, Mol Endocrinol, 1992; PMID 1333056)
  • Reviews cover the receptor's signal transduction and synthetic growth hormone-releasing peptides. (Mayo et al., Ann N Y Acad Sci, 1996; PMID 8993403)

Mechanism, every cited study and the regulator records are on the Sermorelin page of the research library. Papers are listed by what they measured, not as evidence of any use.

How is Sermorelin supplied and stored?

Sermorelin is supplied as a lyophilized (freeze-dried) powder in a sealed vial, for in-vitro laboratory research only. Our stated storage condition for the sealed lyophilized vial is 2 to 8 °C. The label and the lot certificate carry the lot-specific storage condition and expiry date.

What is the regulatory status of Sermorelin?

The EMA medicines database (checked 5 October 2026) lists no centrally authorised medicine naming Sermorelin as an active substance. National authorisations are not in that dataset.

No SmPC, PIL or PAR document in MHRA Products matches the exact name (checked 5 October 2026).

The WADA 2026 Prohibited List names this substance under S2.2.4. A WADA entry is a sporting rule, not a statement about legality outside sport.

A regulator record is information about a database entry. It is not advice and not a statement that any use is lawful or unlawful in any country. How regulators approach research peptides.
