Research-Grade Compound

KLOW Blend is a four-peptide regenerative research formulation combining KPV (Lys-Pro-Val), GHK-Cu (glycyl-L-histidyl-L-lysine copper complex), BPC-157 (Body Protection Compound-157, a 15-amino-acid gastric pentadecapeptide), and TB-500 (synthetic Thymosin β-4). The name is an acronym of its components — K for KPV, L for the lysine-containing copper tripeptide, O and W following the earlier GLOW naming convention.

Purity standard: KLOW Blend is sourced to ≥99% by HPLC — sourcing spec.

Buying KLOW Blend — Frequently Asked Questions

What purity standard does Peptide.Express use for KLOW Blend?

Each component is sourced against a ≥99% HPLC specification. Where a certificate reports LC-MS/MS or composition, those lines are the results for that lot. A Certificate of Analysis is published where one is on file.

Where is the Certificate of Analysis for KLOW Blend?

The batch-specific CoA is available on this page and in the Peptide.Express lab results library. Sourced against a ≥99% HPLC purity specification. Third-party Certificates of Analysis are published where on file. If you have a vial in hand, the batch number on the label maps to a specific CoA.

What testing does KLOW Blend undergo before shipping?

Where a certificate is on file, it shows the assays that laboratory reported. Those can include reverse-phase HPLC, LC-MS/MS, an endotoxin result, and visual QC. A missing line is not a pass and is not proof the assay never ran.

How should KLOW Blend be stored before and after reconstitution?

Lyophilized: -20°C, desiccated, protected from light, stable for 24 months from manufacture. Reconstituted: 2–8°C, used within 14–28 days. Do not freeze the reconstituted solution and avoid repeated freeze-thaw cycles — the copper complex in particular is sensitive to repeated thermal stress.
