The blue tint comes from the copper ion bound in GHK-Cu, one of KLOW's four components. Color intensity can vary batch to batch and is not itself a purity indicator - COA and HPLC data are the reliable verification method.

Quick answer: KLOW peptide is a four-component research blend containing GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg, providing 80mg of total research material per vial . The name is shorthand for its components, combined into one vial for laboratory research rather than sold as four separate compounds.

How to read this page. KLOW is a research supply format, not a clinically studied entity in its own right. We describe what each component is and where the evidence stops - not a recommendation, a dose, or a claim about the combined formulation.

What Is in KLOW 80mg?

Every KLOW research vial is formulated to the same fixed ratio:

Compound Amount GHK-Cu 50mg BPC-157 10mg TB-500 10mg KPV 10mg Total 80mg

The blend is supplied as sterile lyophilised powder strictly for in-vitro and preclinical research. Reconstitution and handling are laboratory procedures outside the scope of this article - nothing here is dosing or administration guidance.

KLOW Is a Blend, Not a Single Peptide

Unlike a single-compound research vial, KLOW combines four independently sourced research peptides into one vial at a declared ratio. That distinction matters for how the evidence should be read: GHK-Cu, BPC-157, TB-500 and KPV each have their own separate research literature, but no study has characterised the four of them administered together as a fixed blend. Evidence on the individual components should not be treated as evidence for the combined KLOW formulation.

GHK-Cu 50mg

GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) studied for extracellular-matrix remodelling and collagen signalling in dermal fibroblast models. It is the largest component of KLOW by mass and the source of the blend's blue tint. See our GHK-Cu copper peptide guide for the full compound profile.

BPC-157 10mg

BPC-157 is a synthetic pentadecapeptide studied for angiogenic and tissue-repair signalling in preclinical models. Read the full BPC-157 research guide.

TB-500 10mg

TB-500, a synthetic thymosin beta-4 fragment, is studied for actin binding and cell-migration signalling. See the TB-500 research overview.

KPV 10mg

KPV is the C-terminal tripeptide (Lys-Pro-Val) of alpha-melanocyte-stimulating hormone, studied for anti-inflammatory signalling that appears to work independently of the melanocortin receptors the parent hormone acts through. It is the component that separates KLOW from the three-part GLOW blend.

Why Is KLOW Blue?

The blue color researchers see in KLOW vials comes from the copper ion bound in GHK-Cu. Color intensity can vary batch to batch and is not itself a purity indicator - a batch-specific Certificate of Analysis and HPLC purity data are the reliable way to verify a vial.

KLOW vs GLOW

GLOW is the three-component predecessor to KLOW - GHK-Cu, BPC-157 and TB-500, 70mg total. KLOW adds KPV for a four-component, 80mg formulation. See the full KLOW vs GLOW comparison for the side-by-side breakdown.

Single Vial vs 10-Vial Availability

New-U Research Compounds supplies KLOW 80mg strictly for laboratory research as a sealed 10-vial research pack , with a single-vial sample available as an add-on for laboratories and independent researchers evaluating the blend at smaller scale first.

Frequently Asked Questions

What is KLOW peptide made of? KLOW is a four-component research blend of GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg - 80mg total per vial.

Is KLOW a single peptide or a blend? KLOW is a blend of four separate research peptides combined into one vial, not a single molecular entity - each component has its own independent literature and clearance profile.

Why is KLOW peptide blue? The blue color comes from the copper ion bound in GHK-Cu, one of KLOW's four components.

Is there research on the combined KLOW formulation itself? Most published research addresses the individual components rather than the combined four-part blend. Evidence on KLOW as a fixed formulation is limited and should not be conflated with single-compound findings.

What is the total peptide content of one KLOW vial? 80mg per vial, made up of GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg.

Research use only. KLOW is supplied strictly for in-vitro and preclinical laboratory research. Nothing on this page is dosing guidance, administration instructions, or a human-use recommendation. Evidence on the individual components (GHK-Cu, BPC-157, TB-500, KPV) is not evidence for the combined blend.
