4-peptide research blend (BPC-157 + TB-500 + GHK-Cu + KPV) — wholesale

For research use only · Not for human consumption · Not for veterinary use. This product is supplied for in-vitro research, analytical method development, and laboratory reference standard use only. Not approved for human or veterinary administration. Buyer is responsible for end-use classification in the destination jurisdiction.

Overview

The BPC-157 + TB-500 + GHK-Cu + KPV 4-peptide blend is a pre-blended research compound supplied as a single lyophilized vial containing four independently verified peptide components at a defined mass ratio. The four components are BPC-157 (15 amino acids), TB-500 (44 amino acids, Thymosin β4 fragment), GHK-Cu (3 amino acids complexed with copper), and KPV (3 amino acids, Lys-Pro-Val). Each component is verified by HPLC and mass spectrometry independently before blending, and the final blended vial carries a multi-component Certificate of Analysis that documents the per-component purity, the per-vial quantitation, and the blending ratio. SPK Pharma India supplies the 4-peptide blend as a research convenience SKU for in-vitro cell-based assays, tissue repair pathway research, and analytical method development.

Specifications

Research context

The four components of this blend span the BPC / Thymosin β4 / copper tripeptide / α-MSH-fragment research domains. BPC-157 is studied in cell-based assays of nitric oxide pathway dynamics and growth factor signalling. TB-500, as a Thymosin β4 fragment, is studied in cell-based assays of actin sequestration and cell migration. GHK-Cu is studied in cell-based assays of extracellular matrix remodelling. KPV is studied as a research tool for the C-terminal tripeptide of α-melanocyte-stimulating hormone (α-MSH) in cell-based assays of inflammation pathway components.

The 4-peptide blend is supplied for research contexts where the four compounds are run in parallel in the same assay plate, eliminating the per-vial reconstitution and per-component dilution steps that would otherwise be required. The blending ratio is defined at the time of compounding and is documented on the multi-component COA. Custom ratios are available on application. SPK Pharma India does not make therapeutic, clinical, diagnostic, or dosing claims for this product. The compound is supplied strictly for in-vitro research, analytical method development, and reference-standard work.

For researchers new to the compound, the standard analytical reference points are the per-component CAS numbers, the per-component sequences, the lyophilized powder form, and the documented per-component purity threshold (≥99% HPLC). The full per-component amino acid sequences are disclosed on the lot-matched COA and on the product specification sheet.

Packaging and supply

• 5 mg + 5 mg + 5 mg + 5 mg blend vial — for method development, parallel cell-based assays, and reference-standard qualification. Standard MOQ: 5 vials.
• 10 mg + 10 mg + 10 mg + 10 mg blend vial — for ongoing research programmes with higher per-assay demand. Standard MOQ: 2 vials.
• Custom ratio — on application, with the specific ratio and per-component mass documented on the COA.

Distributor pricing is available on application. Annual supply contracts with scheduled recurring dispatch are available for repeat buyers. Lead time for in-stock SKUs is typically 5 business days from purchase order confirmation; lead time for scheduled production is typically 4 to 6 weeks.

Quality and documentation

Every lot of the 4-peptide blend ships with a multi-component lot-matched Certificate of Analysis documenting per-component identity (mass spectrometry and amino acid analysis), per-component purity (HPLC, verified before blending), per-vial quantitation, blending ratio, lot number, and synthesis batch reference. A representative sample of every lot is independently verified by a third-party analytical laboratory before release. MSDS is supplied with every shipment. The COA template, the lot-traceability workflow, and the third-party verification scope are documented on the Quality page.

Storage and handling

• Store at -20°C in the original sealed container.
• Protect from light and moisture.
• Allow the sealed container to reach room temperature before opening, to avoid condensation.
• Reconstitute in sterile, low-endotoxin research-grade water or in a mild buffer at the working concentration required by the assay.
• Do not refreeze once reconstituted; aliquot and store at working concentration.
• Avoid vigorous vortexing; allow gentle dissolution to minimise aggregation.

Shipping

The 4-peptide blend is shipped lyophilized in sealed vials within temperature-validated packaging. International lanes are routed through dedicated life-science logistics partners with cold-chain handling. Standard dispatch is within 5 business days of purchase order confirmation. SPK Pharma India ships to the United States, the European Union, the United Kingdom, Canada, MENA, APAC, and LATAM. Full export documentation, including commercial invoice, packing list, certificate of origin, COA, and MSDS, is included with every shipment. Destination-specific documentation is supported on request.
