KLOW Blend 80mg
Lot VR06015260180 · HPLC purity >99.5% · Vanguard Laboratory · report V260618-8 004 · reported 1 Jul 2026
What this is
A research blend of four peptides — KPV, GHK-Cu, BPC-157, and TB-500 — in one reconstitutable vial. The 80mg on the label is the combined mass across all four.
KLOW is the four-compound version of a formulation family you will also find here as a three-compound blend. The difference between them is one peptide:
- GLOW 70mg — GHK-Cu + BPC-157 + TB-500.
- KLOW 80mg — the same three, plus KPV.
KPV is the addition, and it is the reason the blend has a different letter in front of it. It is a tripeptide — lysine-proline-valine — that is the C-terminal fragment of the alpha-MSH hormone. Adding it brings a melanocortin-pathway component into a formulation that is otherwise about copper signalling and tissue repair.
Research profile
Combines a melanocortin-derived tripeptide, a copper-binding tripeptide, and two of the most co-studied tissue-repair peptides; a common pairing in skin- and recovery-focused research.
Four components, four separate research literatures. Here is how each is framed, in the same hedged register we use throughout:
KPV. A tripeptide (lysine-proline-valine), the C-terminal fragment of the alpha-MSH hormone. Studied in inflammation research as a model for melanocortin-pathway signaling, without the pigmentary activity of the full hormone. That last clause is the point of using the fragment rather than the whole molecule.
GHK-Cu. A naturally occurring copper-binding tripeptide, glycyl-L-histidyl-L-lysine, complexed with copper. Studied widely in skin and tissue-repair research as a model for copper-peptide signaling and collagen-related pathways.
BPC-157. A synthetic 15-amino-acid peptide, one of the most-cited in tissue-repair research. Not an approved drug.
TB-500. A synthetic fragment of thymosin beta-4, studied in cell-migration research as a model for actin-binding and angiogenic pathways.
As with every blend on this site: research on the four together is far thinner than research on each alone. Co-formulation is a convenience decision, not a claim of combined effect.

Lab testing and this lot's certificate
Every lot in this catalog is tested by Vanguard Laboratory, an independent A2LA-accredited lab (A2LA certificate #6377.01.01) — chromatographic purity by HPLC-UV/VIS, quantity by assay, endotoxin by LAL.
Lot VR06015260180 is covered by published report V260618-8 004, dated 1 July 2026. Chromatographic purity came back at >99.50% (±0.18%), and the endotoxin row on that certificate reads Pass — <5.00 EU/mg, which is the lab's own printed verdict rather than one we worked out.
On a four-component blend, the assay line is the number that matters most, because it is what tells you how the 80mg is actually split. Here it is, straight off the certificate: GHK-Cu 65.60mg, BPC-157 12.37mg, TB-500 10.15mg and KPV 11.90mg, quantified individually by HPLC-UV/VIS. Our GLOW blend certificate breaks its 70mg out the same way.
The certificate is on this page, and you can also look it up directly at Vanguard — the report number and the lot on the certificate are the ones printed above.
Handling and storage
Lyophilized blend. One reconstitution puts all four peptides into solution together.
Sealed at −20°C, protected from light — the GHK-Cu component makes this blend more light-sensitive than a plain peptide vial, and it is also what gives the powder its colour.
One diluent addition puts all four compounds into solution at a fixed ratio. That is the trade: fewer steps, no ratio control. If your protocol needs the four masses independently, all four are available as single-compound vials.
The reconstitution reference on this page converts diluent volume into concentration. It is a reference for in-vitro laboratory handling only. Its outputs describe the physical properties of the reconstituted vial — concentration and mass drawn — and are not dosing guidance, administration instructions, or medical advice.
Bacteriostatic water sold separately.
Questions
What is the difference between KLOW and GLOW?
One peptide. GLOW is GHK-Cu + BPC-157 + TB-500 at 70mg combined. KLOW is those three plus KPV at 80mg combined.
What does KPV add?
A melanocortin-pathway component. KPV is the C-terminal tripeptide fragment of alpha-MSH, studied in inflammation research as a model for melanocortin signalling without the pigmentary activity of the full hormone.
Is there a published certificate?
Yes — Vanguard Laboratory report V260618-8 004, covering lot VR06015260180. It is linked right here on this page, and you can pull it up by lot on the lab tests page.
How is the 80mg divided across four compounds?
The split is set at formulation and confirmed by assay on the certificate. For lot VR06015260180 the certificate quantifies each one separately: GHK-Cu 65.60mg, BPC-157 12.37mg, TB-500 10.15mg and KPV 11.90mg.
Can I buy the four separately?
Yes: KPV 10mg, GHK-Cu 50mg, BPC-157 5mg, TB-500 10mg.
