KLOW Blend (BPC-157 · TB-500 · GHK-Cu · KPV)
Four-peptide research blend: BPC-157, TB-500, GHK-Cu and KPV in one 80 mg vial
- FormLyophilized powder in a sealed glass vial
- Research areasTissue repair, extracellular matrix remodelling, mucosal and inflammatory signalling
Overview
KLOW Blend is a co-formulated research preparation that places four widely studied peptides — BPC-157, TB-500, GHK-Cu and KPV — into a single lyophilized 80 mg vial. The name is an acronym of its components, and the formulation exists because laboratories examining tissue-repair signalling frequently run these four molecules together rather than in isolation. Consolidating them removes three separate reconstitution steps and the dilution error that comes with them.
Each component belongs to a different peptide family. BPC-157 is a synthetic gastric pentadecapeptide derived from a sequence identified in human gastric juice. TB-500 is the actin-binding fragment of thymosin beta-4. GHK-Cu is a copper(II)-complexed tripeptide first isolated from human plasma. KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone. Their published research literatures overlap around wound models, extracellular matrix turnover and inflammatory signalling, which is why they are grouped.

Working out the concentration
A lyophilized vial carries a mass on the label and no concentration anywhere, so the first calculation of any protocol is the reconstitution one. The peptide concentration calculator converts vial mass plus diluent volume into mg/mL, and back into the draw volume for a given mass.
Certificate of analysis
Every lot of KLOW Blend (BPC-157 · TB-500 · GHK-Cu · KPV) is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Purity: ≥99% by HPLC per component — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about KLOW Blend (BPC-157 · TB-500 · GHK-Cu · KPV)
What does KLOW stand for?
KLOW is an acronym drawn from the four peptides in the vial: KPV, and the letters associated with the copper peptide GHK-Cu, BPC-157 and TB-500 in common laboratory shorthand. It is a formulation name used across the research-peptide market rather than a trademarked compound.
How is the 80 mg divided between the four peptides?
A typical KLOW vial is weighted toward GHK-Cu at 50 mg, with BPC-157, TB-500 and KPV at 10 mg each. The exact per-component content for the lot you receive is stated on that lot's certificate of analysis, which is the authoritative figure.
Is this blend third-party tested?
Yes. Every lot is analysed by HPLC for identity and purity and is released against a lot-matched certificate of analysis. Because this is a blend, the COA reports each component separately. Request the current lot COA before ordering if you need to review it first.
Why buy a blend instead of four separate vials?
A single vial means one reconstitution, one storage container and one dilution calculation, which reduces handling error in multi-compound study designs. Separate vials are the better choice if your protocol needs to vary the ratio between components, since a blend fixes that ratio.
How should the vial be stored before it is opened?
Keep the sealed lyophilized vial at −20 °C, away from light and moisture. In that state the powder is stable for extended periods. Short transit at ambient temperature is normal for lyophilized peptide and does not require refrigerated shipping.
