Sermorelin is the common name for GHRH(1-29)NH2, a 29-amino-acid peptide fragment of human growth hormone-releasing hormone. Helix Bio supplies sermorelin acetate as a lyophilized research compound, packaged for laboratory and academic study of the GHRH receptor and the pituitary growth hormone pathway. This listing is for a research chemical only. It is not a drug, dietary supplement, or finished pharmaceutical product, and it is not sold, labeled, or intended for human or animal use of any kind. It is intended exclusively for qualified researchers and laboratories operating under appropriate institutional protocols.

Sermorelin was originally developed and studied as a diagnostic and investigational agent for growth hormone secretion, and was marketed in the United States decades ago under the trade name Geref before being withdrawn from the market by its manufacturer in 2002. Today, sermorelin acetate is manufactured and distributed almost exclusively as a research-use-only (RUO) compound, used by laboratories to study GHRH receptor binding, pituitary somatotroph physiology, and peptide structure-activity relationships.
Sermorelin corresponds to the first 29 amino acids of endogenous GHRH — the shortest fragment of the native hormone that retains full receptor-binding activity in published research. Helix Bio's sermorelin is supplied as the acetate salt, in lyophilized (freeze-dried) powder form, identified by CAS number 86168-78-7, with a molecular formula of C149H246N44O42S and a molecular weight of approximately 3,357.9 g/mol.
This product exists to support in vitro and in vivo laboratory research into the GHRH signaling pathway, endocrine regulation, and comparative peptide chemistry. It is manufactured for controlled research settings and is not formulated, tested, or approved for therapeutic, diagnostic, cosmetic, or any other human or veterinary use.
Researchers selecting a sermorelin source are typically comparing suppliers on documentation, sourcing transparency, and consistency — not on marketing claims. Helix Bio positions its sermorelin acetate around exactly those criteria: a clearly identified compound (CAS 86168-78-7), a stated acetate salt form, and packaging built for laboratory handling rather than consumer retail. For a compound this well-studied academically, the differentiator is rarely the molecule itself — it's whether the supplier can back up what's in the vial.
This product is not intended for individual consumers, is not a supplement or over-the-counter product, and is not intended for personal, human, or veterinary use.

Published literature on sermorelin and GHRH(1-29) spans several research areas relevant to laboratories working with this compound:
This is a summary of research directions reflected in published literature, not a claim of efficacy, safety, or suitability for any application outside a controlled laboratory setting. It is not medical, dosing, or treatment information.
Reputable research-peptide suppliers typically support each batch with high-performance liquid chromatography (HPLC) data to confirm purity, and mass spectrometry to confirm molecular identity, summarized in a certificate of analysis (COA) tied to a specific lot number. If third-party (independent lab) testing is used, that should be stated plainly, since "third-party tested" is a claim researchers specifically look for and one that shouldn't be implied unless it's accurate.
Specific purity percentages, certifications, or lab names are published only once verified against current documentation.
Helix Bio does not provide reconstitution, dosing, or administration instructions. Any handling beyond storage of the sealed research compound should follow the purchasing institution's own laboratory protocols and be performed by qualified personnel.
Helix Bio ships sermorelin research orders within the United States. Packaging is intended to help preserve the stability of a lyophilized peptide in transit. Exact shipping timelines, carriers, and packaging materials should be confirmed against Helix Bio's current shipping policy before ordering.
Sermorelin acetate sold by Helix Bio is intended strictly for laboratory research use by qualified professionals and institutions. It is not a drug, biologic, dietary supplement, food, or cosmetic, and it has not been evaluated or approved by the FDA for human or animal use. This product is not for human consumption, injection, or any form of personal use, and no claims are made regarding safety, efficacy, or suitability for any therapeutic, diagnostic, or performance purpose.
By purchasing this product, the buyer represents that they are a qualified researcher or are purchasing on behalf of a laboratory or research institution, and that the product will be used solely for legitimate research purposes in compliance with all applicable federal, state, and institutional regulations.
