Hexarelin

Hexarelin is supplied as a catalogued research material in 5mg.

The catalogue name identifies hexarelin/examorelin but does not state whether the vial contains the free peptide, acetate, TFA or another form. Parent and acetate records are chemically distinct, so formula, mass and registry identifiers remain conditional on the matching batch identity report [1,2].

Chemical properties and registry information

Registry values apply only to the specific molecular entity, sequence, termini and material form. Batch records take precedence over family-level literature identifiers.

A potent, synthetic growth hormone secretagogue that acts as an agonist at the ghrelin/growth hormone secretagogue receptor (GHSR).

Research background and published evidence

Published research

IUPHAR classifies examorelin/hexarelin as a peptidic growth-hormone secretagogue. A defined reference can be used in GHSR ligand-binding, receptor-signalling and analytical-assay research when sequence, stereochemistry and salt form are controlled [3].

Current scientific understanding

Receptor classification and experimental endocrine observations do not establish long-term safety, efficacy, dosage, administration, or medicine authorization. They also do not verify identity, purity, amount or salt form for this catalogue batch [1–3].

Hexarelin is specifically covered by current anti-doping restrictions [4].

Technical comparison

Quality and testing

Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot or similarly named material must not be treated as evidence for this product.

Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.

Laboratory handling and storage

Store and handle only under the conditions stated on the product label, batch CoA and SDS. Keep the container secured, correctly identified and protected from contamination. Do not infer storage, solvent compatibility or stability from a related compound.

Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment and waste disposal should follow the applicable SDS and the institution's approved procedures.

Frequently Asked Questions

Do the CAS number and PubChem CID apply to every batch form?

Only when the exact sequence or structure, termini, conjugation, salt or counter-ion and hydration state match. The batch CoA and SDS govern; a related-compound identifier must not be substituted.

What does an analytical purity result mean?

It is method- and report-specific. For example, an HPLC area percentage is not automatically the same as identity, net content, sterility, endotoxin status or absence of elemental impurities.

How should the material be stored and handled?

Follow the exact label, batch CoA and SDS together with the institution's risk assessment. Use only storage and stability information linked to the exact material form and batch.
