Classic GHS-R1a hexapeptide reference studied in receptor-binding and secretagogue structure-activity research. ≥99% HPLC. Research use only. This guide covers identity, published research context, procurement checks, and storage — RUO only, no clinical claims.
What GHRP-6 is in published research
GHRP-6 is a synthetic hexapeptide used as a classic reference for growth hormone secretagogue receptor research. Published laboratory work uses GHRP-6 in GHS-R1a binding, concentration-response, and SAR studies.
Because GHRP-6 is structurally close to hexarelin and GHRP-2, it is useful as a comparator in selectivity panels. Each lot ships with HPLC and MS data to support sequence-specific procurement.
Store sealed vials at -20 °C protected from light. Reconstitute in bacteriostatic water or compatible lab buffer, then aliquot before freezing to reduce freeze/thaw exposure.
CoA covers identity, purity, and net peptide content. Batch records are filed by SKU and lot.
The material class "Growth hormone releasing peptide (research)" helps procurement teams group GHRP-6 with related reference peptides during comparative studies.
Sequence and identity
GHRP-6 identity on the catalog: Common name: GHRP-6; Sequence: His-D-Trp-Ala-Trp-D-Phe-Lys-NH2; Length: 6 residues; Molecular formula: C46H56N12O6; Molecular weight: 873.01 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 GHRP-6 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 GHRP-6 pharmacology in vitro.
Report effect sizes with lot number and CoA reference so results can be reproduced if the same GHRP-6 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 GHRP-6 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 GHRP-6 working stocks.
Attach purchase order, packing list, and CoA in one audit folder per lot.
Storage and reconstitution
Store lyophilized GHRP-6 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 GHRP-6, 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 GHRP-6 with adjacent catalog references often evaluate the following SKUs in parallel plates:
Use matched reconstitution buffers and stock concentrations when running comparative binding or signaling assays.
Frequently asked questions
Is GHRP-6 for clinical programs?
No. It is sold for research use only (RUO) to qualified buyers.
What purity should we expect for GHRP-6?
Listings target ≥99% HPLC with MS identity on the lot CoA. Verify on receipt, not from marketing copy alone.
How do we calculate molarity for GHRP-6?
Use net peptide content from the CoA divided by molecular weight, then divide by reconstitution volume.
Can we mix lots of GHRP-6 in one stock?
Avoid mixing lots unless your protocol explicitly requires it. Mixed lots break traceability.
Where is the GHRP-6 product listing?
View the catalog PDP for GHRP-6 for variant SKUs and quote or purchase options.
