Hexarelin: Research overview, identity, and laboratory handling guide

Synthetic hexapeptide secretagogue studied in vitro for GHS-R1a receptor signaling and structure-activity comparisons. ≥99% HPLC. Research use only. This guide covers identity, published research context, procurement checks, and storage — RUO only, no clinical claims.

What Hexarelin is in published research

Hexarelin is a synthetic growth hormone secretagogue hexapeptide used in laboratory work around GHS-R1a binding and downstream cAMP or calcium signaling. It is often compared against GHRP-6 and ipamorelin in receptor selectivity panels.

The D-2-methyl-tryptophan residue differentiates hexarelin from related GHRP analogues. CoA documentation verifies identity by MS and purity by HPLC so labs can distinguish the backbone during comparative assay setup.

Hold lyophilized vials at -20 °C, sealed and protected from light. Reconstitute with bacteriostatic water and aliquot reconstituted stock into single-use working volumes.

CoA includes MS identity, HPLC purity, and net peptide content. Lot records are retained against the SKU for audit support.

The material class "Growth hormone secretagogue (research)" helps procurement teams group Hexarelin with related reference peptides during comparative studies.

Sequence and identity

Hexarelin identity on the catalog: Common name: Hexarelin; Sequence: His-D-2-Me-Trp-Ala-Trp-D-Phe-Lys-NH2; Length: 6 residues; Molecular formula: C47H58N12O6; Molecular weight: 887.05 g/mol; Appearance: White lyophilized powder; Purity (HPLC): ≥ 99%; Net peptide: Listed on CoA; Solubility: Soluble in bacteriostatic water. Copy these into receiving and LIMS before reconstitution.

Mechanisms studied in published research

Mechanism-focused research on Hexarelin is typically conducted in cell lines or biochemical preparations that express the relevant receptor or binding protein for its class.

Design controls that include scrambled-sequence or orthogonal-receptor negative controls when your protocol evaluates Hexarelin pharmacology in vitro.

Report effect sizes with lot number and CoA reference so results can be reproduced if the same Hexarelin SKU is reordered later.

Avoid extrapolating in vitro binding or signaling readouts to whole-organism outcomes; RUO materials are not qualified for clinical investigation.

Procurement and identity verification

Request the lot-specific CoA for Hexarelin at receipt. Verify SKU, variant size if applicable, and identity mass before the lot enters general storage.

Compare HPLC purity to your internal minimum for the peptide family. File chromatogram excerpts when your QMS requires raw data.

Enter net peptide content from the CoA into inventory before calculating molarity for Hexarelin working stocks.

Attach purchase order, packing list, and CoA in one audit folder per lot.

Storage and reconstitution

Store lyophilized Hexarelin sealed at -20 °C protected from light unless the CoA states otherwise.

Reconstitute with bacteriostatic water or a buffer validated for your assay pH. Aliquot to limit freeze-thaw.

For oxidation-sensitive sequences in Hexarelin, minimize open-vial time at room temperature during weighing.

See our lyophilized storage guide for institution-scale SOP examples and aliquot labeling conventions.

Comparative reference points

Researchers comparing Hexarelin with adjacent catalog references often evaluate the following SKUs in parallel plates:

Ipamorelin (ipamorelin) — compare identity table and CoA fields side by side.

Use matched reconstitution buffers and stock concentrations when running comparative binding or signaling assays.
