KLOW is a multi-peptide research blend designed for laboratory studies involving cellular signaling, tissue remodeling, regenerative pathways, and inflammatory-response mechanisms.
What is in it
KLOW is a four-peptide blend. The proportions below are taken from the certificate of analysis; GHK-Cu makes up most of the peptide mass, so this is not four equal parts.
GHK-Cu
Copper-binding tripeptide
~63%
BPC-157
Fifteen-residue gastric peptide
~14%
KPV
Lys-Pro-Val tripeptide
~12%
TB-500
Thymosin beta 4 fragment
~11%
Exact per-component quantities and HPLC purity are on the certificate of analysis. For what each component is and why the blend is weighted this way, read the KLOW research guide.
Multi-Peptide Research
Combines multiple research peptides in a single formulation for studying interconnected biological pathways.
Tissue Remodeling
Designed for experimental research examining tissue remodeling and cellular repair processes.
Cellular Signaling
Studied in laboratory models involving cellular communication and signaling pathways.
Regenerative Research
Suitable for research exploring regenerative processes and biological responses associated with tissue maintenance.
What is in the Klow blend
Klow is a four-peptide blend rather than a single compound, and the proportions matter more than the total. Its certificate of analysis gives the composition as roughly 63% GHK-Cu, 14% BPC-157, 12% KPV and 11% TB-500 by mass, at a stated purity above 99.5%.
That makes it predominantly a copper-peptide preparation with three shorter peptides alongside. Anyone reasoning about the blend should start from that: GHK-Cu is not a minor component here, it is the bulk of the material.
Why a blend behaves differently from its parts
Blends are not simply four products in one vial. GHK-Cu is a coordination complex in which copper(II) is held by the peptide — the copper is part of the molecule being studied, not an additive — and that chemistry does not disappear because three other peptides share the vial.
Practically, this means reconstitution and handling should follow the most demanding component, and that comparisons against single-compound work need to account for the fact that the mass on the label is shared four ways.
Handling and reconstitution
Standard lyophilised peptide handling applies. Keep the sealed vial cold and dark until it is used. Reconstitute by running bacteriostatic water slowly down the inside wall of the vial rather than firing it onto the powder cake, and let it dissolve without shaking — swirl gently if it needs help.
The concentration you end up with is set by how much water you add, not by the vial size. Our reconstitution calculator turns vial mass and water volume into a concentration and a syringe reading.
Storage
Sealed and lyophilised: refrigerated, protected from light. In solution: refrigerated, and treat time at room temperature as a cost. Avoid repeated freeze-thaw once reconstituted.
What ships, and what is on the certificate
The vial ships sealed as it was filled. Every compound in the catalogue is tested by an outside laboratory — Vanguard Laboratory in Olympia, Washington — and the certificate is published in full rather than summarised.
The certificate reports chromatographic purity by HPLC with the chromatogram visible, the measured quantity in milligrams, and an endotoxin result by LAL. Measured quantity usually reads slightly above the label, which is normal: fills are targeted high so every vial meets its stated content.
Frequently asked questions
What is actually in Klow?
Its certificate gives roughly 63% GHK-Cu, 14% BPC-157, 12% KPV and 11% TB-500 by mass, at above 99.5% purity. It is predominantly a copper-peptide preparation.
Does the label mass apply to each peptide?
No. The stated mass is the total for the blend, shared across four components in the proportions above. Each individual peptide is present at a fraction of the label figure.
Does the copper in GHK-Cu matter?
Yes. GHK-Cu is a coordination complex, not a peptide with copper added alongside it. Essentially the whole research literature concerns the complex rather than the free peptide.
How should it be reconstituted?
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve without shaking. The reconstitution calculator will convert vial mass and water volume into a concentration and a syringe reading.
Does it come with a certificate of analysis?
Yes. Every compound is tested by an independent laboratory and the full certificate, chromatogram included, is published on the site rather than summarised.
Is this a medicine?
No. It is sold for in-vitro laboratory research use only. It is not a drug, supplement or cosmetic, and is not for human or veterinary use.
