Quick answer: an 80mg KLOW research vial contains four compounds in a fixed ratio - GHK-Cu 50mg (62.5%), BPC-157 10mg (12.5%), TB-500 10mg (12.5%) and KPV 10mg (12.5%). This page breaks down the exact composition, why it is formulated this way, and how to verify a batch before use.

Not the same as our definitional guide. This page covers the exact 80mg specification. For a plain-English introduction to KLOW, see What Is KLOW Peptide?

KLOW 80mg Composition

Compound Per vial Share GHK-Cu 50mg 62.5% BPC-157 10mg 12.5% TB-500 10mg 12.5% KPV 10mg 12.5% Total 80mg 100%

Why KLOW Is a Blend, Not a Single Peptide

A blend vial combines independently manufactured research peptides at a declared ratio, rather than a single synthesized molecule. Composition claims are only as reliable as the batch-specific analytical testing behind them - see the verification section below before treating any vial's contents as confirmed.

GHK-Cu 50mg

A copper-binding tripeptide and the largest component of KLOW by mass, contributing the blend's blue coloration.

BPC-157 10mg

A synthetic 15-amino-acid peptide fragment, one of three equal-minority components at 10mg.

TB-500 10mg

A synthetic thymosin beta-4 fragment, 10mg per vial.

KPV 10mg

A tripeptide fragment (Lys-Pro-Val) derived from alpha-MSH - the component that differentiates KLOW from the three-part GLOW blend.

Why KLOW Is Commonly Supplied as 80mg

The 50/10/10/10mg ratio is the standard commercial formulation researchers reference when discussing "KLOW." A vial with a different ratio or component list is a different product and should be verified accordingly rather than assumed to match this specification.

Lyophilised KLOW Research Material

KLOW is supplied as sterile lyophilised (freeze-dried) powder for laboratory research. Reconstitution and handling are standard laboratory procedures outside the scope of this specification page - nothing here is dosing or administration guidance.

KLOW Single Vial vs 10-Vial Pack

New-U Research Compounds provides KLOW 80mg as a sealed 10-vial research pack , with a single-vial sample available as an add-on.

10-Vial Pack

Positioned for repeat research, consistent supply, larger laboratory requirements, and the same defined formulation across every vial in the pack.

Single-Vial Sample

Positioned for smaller procurement requirements, preliminary analytical work, and compound evaluation before a larger order.

How to Verify a KLOW Research Blend

Before treating a vial's contents as confirmed, check:

Exact formulation (50/10/10/10mg)

Current batch/lot number

Independent Certificate of Analysis

HPLC purity

Identity verification where available

Testing date and testing laboratory

Traceable supplier/batch relationship

COA, HPLC and Batch Traceability

A Certificate of Analysis and HPLC purity report demonstrate compound identity and purity for the specific tested batch - not for the product generally. Batch traceability means a specific vial can be matched back to its specific COA and lot. Review the current KLOW batch Certificate of Analysis or browse the full COA library.

Frequently Asked Questions

What is the exact mg breakdown of KLOW 80mg? GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg, totaling 80mg per vial.

Why does KLOW use a 50/10/10/10mg ratio? That ratio is the standard commercial KLOW formulation - it is what distinguishes a genuine KLOW vial from a differently-dosed or differently-composed blend sold under the same name.

Is KLOW supplied as a lyophilised powder? Yes, KLOW research vials are supplied as sterile lyophilised powder for laboratory research.

How can a researcher verify blend accuracy before use? By reviewing the batch-specific Certificate of Analysis, HPLC purity data, and identity verification tied to the vial's lot number.

Does every vial in a 10-vial pack match the same formulation? A sealed 10-vial pack is manufactured to the same declared 80mg formulation across the pack and should share batch/lot traceability - always confirm against the pack's COA.
