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for growth hormone secretion, and was marketed in the United States decades ago under the trade name Geref before being withdrawn from the market by its manufacturer in 2002.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.
