Hexarelin is a synthetic hexapeptide, a chain of six amino acid residues, catalogued as a GHS-R1a agonist. Its molecular formula is C47H58N12O6 and its molecular weight is approximately 887 g/mol. v e r t stocks it as a white lyophilized reference material in a single 10mg vial, sold for laboratory research and educational purposes only.

The molecular formula is C47H58N12O6, which is forty-seven carbon atoms, fifty-eight hydrogen, twelve nitrogen and six oxygen. Worked against standard atomic weights that formula comes to 887.06 g/mol, and the PubChem record carries 887.0. The spread is rounding and the choice of atomic weight table, not a disagreement about which molecule is in the vial. One point worth stating plainly, because catalog listings for peptides often blur it: the formula contains no counter-ion, so 887 g/mol is the mass of the peptide as named rather than of a salt of it.

PubChem CID 6918297, and InChIKey RVWNMGKSNGWLOL-GIIHNPQRSA-N. Those are the two identifiers used on this page and the ones to check the compound against. The InChIKey is the more robust of the pair, because it is derived from the structure itself rather than assigned by a registry: its first block encodes the connectivity, and the blocks that follow encode stereochemistry and protonation state. A catalog number is a pointer to a record; the key is a fingerprint of the molecule.

A certificate is published for the 10mg size at /coa/hexarelin-10mg.pdf. It states the lot, the identity, the appearance as a white lyophilized powder, the molecular formula, the molecular weight, a purity specification of greater than 98 percent, and the analytical data plates behind the figures. Two methods are doing two different jobs. Mass spectrometry establishes identity. Chromatography establishes chromatographic purity, which is a relative figure and not an assay of absolute content. What the document does not state is as important as what it does. It carries no water or moisture content, no residual solvent, no counter-ion or salt content, no peptide content by nitrogen determination, no endotoxin figure and no bioburden figure. Anything absent from the certificate is not certified by it, and a lot is described by its own certificate rather than by a figure carried over from another lot.

The certificates published by v e r t state ultra-high-performance liquid chromatography with mass spectrometry. The number the method produces is an area-percent figure: the integrated area of the main peak divided by the total integrated peak area at the detection wavelength. It measures how much of the chromatographically resolved material is the named species, and it says nothing about water, salt, residual solvent, or any component that does not retain on the column or absorb at that wavelength. The specification is the standing requirement, greater than 98 percent, which every lot has to clear to be released. It is a threshold rather than a measurement, and it is the figure this page cites, because a specification holds across lots and a single lot's measurement does not.

Hexarelin ships in one size, a 10mg vial, as a white lyophilized powder in a sealed container. Lyophilization removes water by sublimation from the frozen state under reduced pressure, which is why the material presents as a light cake or powder rather than a compacted solid, and why it is sensitive to atmospheric moisture once a container is opened. It is supplied dry. It is not a solution, a suspension, a premixed blend or any prepared formulation, and v e r t publishes no preparation guidance of any kind. Storage is desiccated at 68°F (20°C), away from light and moisture.
