Sermorelin Acetate 5mg

Sermorelin acetate is a synthetic 29-amino-acid analogue corresponding to the biologically active N-terminal fragment of growth-hormone-releasing hormone, GHRH(1–29), supplied as the acetate salt. It is studied in growth-hormone-axis and secretagogue research and is supplied by NMChem as a research reference material.

As a GHRH-receptor analogue it belongs to the same mechanism class as CJC-1295 and tesamorelin, and is distinct from the growth-hormone secretagogue-receptor agonists such as ipamorelin and GHRP-2, which reach the same axis through a different receptor. The comparison tool sets the classes side by side.

Note on the acetate salt

This listing is supplied as the acetate rather than the trifluoroacetate salt. That is a deliberate distinction: reversed-phase purification normally leaves a TFA counterion behind, and an explicit salt-exchange step is required to replace it. Acetate is preferred where residual TFA would interfere with a downstream system. The counterion also contributes mass, which is one of the reasons the nominal vial weight overstates the peptide present — molar mass and solution concentration covers the correction, and how research peptides are made explains where the counterion comes from in the first place.

5 mg lyophilised powder, SKU SERM5.

Documentation

A Certificate of Analysis is produced per batch and is available on request against the lot number printed on the vial. Characterised by reversed-phase HPLC for purity and by mass spectrometry for identity. If you have not worked with this kind of report before, how to read a Certificate of Analysis walks through each section, and identity vs purity explains why the two headline numbers answer different questions.

Handling

Supplied lyophilised. Allow the sealed vial to reach room temperature before opening so atmospheric moisture does not condense onto cold glass, add solvent slowly down the vial wall rather than directly onto the cake, and dissolve without vortexing. Store the dry material at −20 °C, protected from light; aliquot reconstituted stock before freezing so no portion is thawed more than once. Storage and stability covers the degradation routes these steps are guarding against, and molar mass and solution concentration covers the arithmetic — including why the nominal vial weight is not the mass of peptide present. Practical procedure is in the reconstitution guide.

Research use only. Supplied for in-vitro research and laboratory use. Not for human or veterinary use, not a medicine, and not for food or cosmetic application. See the compliance page for the framework NMChem operates under.
