Composition

This is a mixture — no single molecular formula. KLOW is a blend of 4separately characterized peptides, so it has no molecular formula, molecular weight, CAS number, or InChIKey of its own. Each identifier below belongs to a component and is listed on that component’s own monograph.

Also known as: KLOW Blend, KLOW peptide blend, GLOW + KPV blend, GHK-Cu / BPC-157 / TB-500 / KPV blend.

The proportions of the components are not standardized across the research-peptide space. A mass partition is sometimes listed by vendors, but no ratio is canonical; Lineará references the composition, not a fixed ratio.

KLOW is GLOW plus KPV. The leading K denotes the added KPV; the name is not presented as a strict letter-by-letter acronym beyond that leading K.

How KLOW relates to GLOW

KLOW is GLOW plus one additional peptide. GLOW combines three components — GHK-Cu, BPC-157, and TB-500; KLOW adds a fourth, KPV. The leading K in the name denotes that added KPV.

Reference context

KLOW is a research-use-only peptide blend — a mixture, not a single molecule — and is defined as the three-component GLOW blend with a fourth peptide, KPV, added. Its four individually characterized research peptides are: KPV, a synthetic tripeptide (Lys-Pro-Val, the C-terminal fragment of α-MSH); GHK-Cu, a copper(II)-binding tripeptide complex; BPC-157, a synthetic 15-residue peptide; and TB-500, the full-length 43-residue thymosin β4 protein. Because it is a mixture, KLOW has no single molecular formula, molecular weight, CAS number, or structure of its own — its identity is fully defined by the identities of its four components, each of which is a separate Lineará reference monograph with its own verified identifiers. All four components fall in the same research class (Regenerative & Cytoprotective). KLOW is supplied and referenced strictly as a characterized research material; Lineará describes what is in it, not what it does.

Frequently asked questions

What is KLOW?
KLOW is a research-use-only peptide blend — a mixture of four separately characterized research peptides: KPV, GHK-Cu, BPC-157, and TB-500. It is defined by its composition, not by a single molecular structure.
What is in the KLOW blend?
Four components: KPV (a synthetic tripeptide), GHK-Cu (a copper-peptide tripeptide complex), BPC-157 (a synthetic 15-residue peptide), and TB-500 (the 43-residue thymosin β4 protein). Each is an individual Lineará monograph. The proportions of the four are not standardized across the research space.
Is KLOW a single molecule with its own formula and CAS number?
No. KLOW is a mixture, so it has no single molecular formula, molecular weight, CAS number, or InChIKey. Those identifiers belong to each component individually and are listed on each component's own page.
How does KLOW differ from GLOW?
KLOW is GLOW plus one additional peptide. GLOW combines three components (GHK-Cu, BPC-157, TB-500); KLOW adds a fourth, KPV. The leading K in the name denotes that added KPV.
How is KLOW different from its individual components?
The components — KPV, GHK-Cu, BPC-157, and TB-500 — are single, fully characterized chemical entities, each with its own formula, mass, and CAS number. KLOW is simply the four combined into one research blend; it adds no new molecule, only the combination.
Is KLOW a peptide?
No. KLOW is a research-peptide blend, not a single molecule — it is a defined mixture of separately characterized peptides, with no molecular formula or CAS number of its own.
How is KLOW stored and reconstituted?
As a research material, KLOW is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.
Does Lineará sell KLOW?
KLOW is listed here only as an identity-and-composition reference for the blend. It is not presented with a price or certificate of analysis on this page; each component is a separate Lineará entry.
Is KLOW approved for human use?
No. KLOW is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
