What is Sermorelin?
Sermorelin is a chain of 29 amino acids. It is the front section of a natural human hormone that tells the pituitary gland, at the base of the brain, to release growth hormone. The full hormone is 44 links long. Researchers found that this shorter piece still does the whole job, and it went on to become the yardstick that later, longer-lasting compounds were measured against.
Technical Specs
Labeled quantity is net peptide content, not gross salt weight.
Sermorelin Research & Reference
What Sermorelin does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.
Certificates of Analysis
Every batch is tested by an independent laboratory before release. The certificate covering this batch of Sermorelin, and its safety data sheet, are below as PDFs, so the figures on this page can be checked against the source.
Frequently Asked Questions
Is Sermorelin independently tested for purity?+−
Yes. Every batch of Sermorelin is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means Sermorelin is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. Sermorelin is legal to purchase in the United States for in vitro and non-clinical laboratory research. Sermorelin acetate was previously the active ingredient of a prescription medicine that is no longer marketed. The material sold here is a research-grade preparation, is not that medicine, and holds no marketing authorisation. As a compound in the growth-hormone-releasing peptide and IGF-1 analog class, Sermorelin appears in section S2 of the WADA Prohibited List for competitive athletes, a separate consideration from its legal research status. Sold strictly for qualified research use, not human or veterinary administration.
How is Sermorelin shipped and stored?+−
Sermorelin ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
