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?

Every component is verified at ≥99% purity by reverse-phase HPLC before blending, with LC-MS/MS confirming molecular identity. The finished blend then receives compositional ratio verification. A batch-specific Certificate of Analysis ships with every order.

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. It lists HPLC purity per component, LC-MS/MS mass confirmation, endotoxin results, batch identifier, and test date. 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?

Reverse-phase HPLC for purity by area-under-curve, LC-MS/MS for molecular weight identity confirmation on each component, LAL endotoxin testing, and visual QC for appearance and particulate matter. All testing is performed by an independent third-party laboratory.

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.
