Peptide Central
What KLOW Research Blend contains, how its 80mg figure is documented, and what published research does and does not establish.
KLOW is a four-component lyophilised research blend supplied by Peptide Central under that catalogue name. One vial contains GHK-Cu, BPC-157, TB-500 and KPV. "KLOW" is a product name, not a compound: it does not identify a molecule in the published literature, so any evidence has to be read component by component.
The catalogue lists it as KLOW Research Blend (80mg). "KLOW", "KLOW blend" and "KLOW 80mg" refer to this one formulation. Searches for a "KLOW pen" or "KGLOW pen" find different products: this item is a lyophilised powder in a vial, not a pre-filled pen.
A multi-component mixture, not a single molecule. A blend has no single HPLC purity figure. Its certificate instead quantifies how much of each active is present.
| Component | What it is | Quantified, batch 100246 |
|---|---|---|
| GHK-Cu | Copper complex of the tripeptide glycyl-L-histidyl-L-lysine | 59.94 mg |
| BPC-157 | Synthetic 15-amino-acid peptide derived from a gastric protein sequence | 11.18 mg |
| TB-500 | Synthetic fragment (Ac-LKKTETQ) of thymosin beta-4 | 10.90 mg |
| KPV | Lys-Pro-Val, the C-terminal tripeptide of alpha-MSH | 10.59 mg |
80mg is the labelled total fill. The certificate for batch 100246 reports 92.61 mg of quantified actives across the four components. A label quantity and an analytical quantification are different measurements, which is why the certificate for the batch, rather than the headline number, is the document to read. GHK-Cu is a copper complex and the copper contributes mass, so check which form a certificate quantifies when comparing figures between suppliers.
KLOW is a catalogue research blend. It is not a licensed medicine in the United Kingdom, none of its components is supplied here as one, and nothing on this page implies availability for human use.
We are not aware of a published study that evaluates this four-component combination, so there is no blend-level evidence to cite. Whatever evidence exists concerns each component on its own.
The component literature is predominantly cell-culture and rodent work, and it differs by compound. Our component articles set out the model behind each finding: GHK-Cu, BPC-157 and TB-500.
A finding for one component does not carry over to the same component inside a mixture. Interactions between components, relative stability and the effect of the proportions are not characterised by those studies.
There is no human data for the blend. Human data for individual components is limited and varies by compound, and none of it transfers to a separately formulated mixture.
A certificate for a blend should state each active separately. Confirm that every component's figure is present rather than a single combined number, and that the batch number on the vial matches the batch on the report.
A certificate establishes identity and quantity for the batch tested. It does not establish biological effect, stability within the mixture, or that another batch is equivalent. Published reports are in the COA library, and the KLOW product page and blends category list the current batch. The guides to reading a peptide COA and understanding HPLC purity cover what those documents can and cannot show.
