KLOW

GHK-Cu + BPC-157 + TB-500 + KPV blend · 10-vial research kit

Combination research blend

KLOW is a four-part research blend — GHK-Cu, BPC-157, TB-500 and KPV — combined in a single vial. It extends the GLOW concept with the addition of KPV, a tripeptide studied in inflammation research.

About KLOW

KLOW builds on the three-peptide GLOW blend by adding KPV, the C-terminal tripeptide of α-MSH studied in inflammation research. All four peptides are presented together in one lyophilized vial; the 80 mg figure is the combined peptide mass per vial.

RetaNord supplies KLOW as fixed kits of 10 or 30 lyophilized vials, each verified at 99%+ identity purity by independent third-party HPLC (Janoshik), and every kit ships with a lot-specific Certificate of Analysis. Supplied for laboratory and in vitro research use only.

How the KLOW blend works

KLOW is the three-peptide GLOW blend plus a fourth: KPV, the C-terminal tripeptide of α-melanocyte-stimulating hormone, which published work associates with anti-inflammatory activity.

The other three work as they do in GLOW — GHK-Cu as a copper carrier and gene-expression modulator, BPC-157 in angiogenic and growth-factor signalling, TB-500 in actin regulation and cell migration. Adding KPV brings an inflammation-signalling component to the same vial. As with GLOW, the published research covers the peptides individually.

What the research shows

Each of the four has its own literature: GHK-Cu in skin regeneration, BPC-157 in wound healing, thymosin β4 in actin regulation, and KPV in α-MSH anti-inflammatory work.

There is no published trial of the four-peptide combination as such. All four are preclinical research compounds, not approved medicines.

Storage & handling

Sealed, lyophilized vials. 2–8 °C for routine storage; −20 °C or below for long-term. Room temperature is for transit and handling only — it is not a storage state for a peptide.

Once reconstituted. Keep at 2–8 °C and never freeze — ice crystals cause irreversible damage. Reconstituted with bacteriostatic water (0.9% benzyl alcohol) a vial is commonly used within about 30 days; with plain sterile water, within 24–48 hours.

Keep vials sealed and protected from light, and minimise freeze–thaw cycles of frozen stock — each cycle costs potency.

KLOW — questions

Do the kits come with a Certificate of Analysis?

Yes — every kit ships with a lot-specific third-party Certificate of Analysis: independent HPLC purity and content testing by Janoshik, with the batch matching your vials. View the current CoA.

How is KLOW different from GLOW?

KLOW is GLOW plus KPV — a four-peptide blend rather than three. Both are supplied as 10-vial research kits for laboratory use only.

Why is this sold as a 10-vial kit?

These research compounds are supplied in fixed kits of 10 identical vials — the standard research quantity. One kit (10 vials) is the minimum order to the EU.

How should KLOW be stored?

Sealed lyophilized vials keep at 2–8 °C, or −20 °C for long-term storage. Once reconstituted, keep refrigerated and never freeze it. See storage & handling for the full detail.

How do I work out the concentration?

The volume of bacteriostatic water you add sets the concentration — the vial size alone does not. Enter your vial size and diluent volume in the reconstitution calculator to calculate the concentration for your assay.

Is the blend itself studied, or just the individual peptides?

Just the individual peptides. Each of the four has its own published literature; there is no published trial of the four-peptide combination as a single entity. The references below are for the constituents.
