Why These Four Compounds Are Blended

KLOW combines four structurally distinct research compounds in a single vial at a fixed mass ratio. It is supplied for laboratories whose protocols examine these compounds together and that prefer a consistent, batch-verified composition over weighing separate materials.

The components are chemically unrelated: GHK-Cu is a copper(II) complex of the tripeptide Gly-His-Lys; BPC-157 is a synthetic 15-residue peptide; TB-500 is a synthetic peptide corresponding to a region of thymosin beta-4; and KPV is the tripeptide Lys-Pro-Val. KLOW differs from GLOW by the addition of KPV as a fourth component.

Handling & Storage

Lyophilized KLOW is stable at 2–8°C when sealed and shielded from light. For storage beyond several months, -20°C is preferred. Avoid repeated freeze-thaw cycles, which can degrade peptide integrity.

Purity & Testing

Every batch is independently analyzed by a third-party laboratory before release. Composition and purity data are reported on the batch Certificate of Analysis. Certificates of Analysis are published for each batch and are available prior to purchase.

Frequently Asked Questions

How does KLOW differ from GLOW?
KLOW contains the same three components as GLOW (GHK-Cu, BPC-157, TB-500) plus KPV as a fourth component.

Can the components be separated?
No. The compounds are combined before lyophilization. Single-compound vials of each are available separately.

What is the component ratio?
GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg per vial, a 5:1:1:1 ratio by mass.

Does it require refrigeration during shipping?
No. The lyophilized powder is stable at ambient temperature for the duration of standard transit. Store at 2–8°C on receipt.

What size is available?
80mg lyophilized vials.
