What is KLOW? Four peptides, one fixed formula
Research context reviewed 5 October 2026PEPTALIAS KLOW is an 80 mg blend: 50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500 and 10 mg KPV. In one line: GHK-Cu is studied for collagen, BPC-157 for nerve fibres and blood vessels, thymosin-related peptides for cell movement, and KPV for inflammation. These interests come from separate studies, not a trial of the four together.
What is in the vial?
| Named component | Label amount | What a study found |
|---|---|---|
| GHK-Cu | 50 mg | Cultured fibroblasts produced more collagen. Read the GHK-Cu guide. |
| BPC-157 | 10 mg | Rats with cut nerves showed faster nerve-fibre regrowth and more blood vessels. Read the BPC-157 guide. |
| TB-500 | 10 mg | A short thymosin beta-4 segment promoted wound repair in aged mice. The TB-500 name alone does not establish that segment's sequence. Read the sequence guide. |
| KPV | 10 mg | In human cell lines, it reduced inflammatory signals; mouse models also showed lower intestinal inflammation measures. |
What does KPV add? The inflammation research question. In the Dalmasso experiments, KPV reduced inflammatory signalling and messenger release in human gut and immune cell lines. It was not a study of KLOW or of people receiving KLOW.
Why choose KLOW instead of four separate vials?
KLOW puts the four named materials in one fixed 50/10/10/10 mg ratio. If your project calls for all four at those amounts, you can select one blend vial instead of four separate products. That is a format choice, not evidence that the combination performs better than the ingredients alone.
Want to study one compound on its own, or vary the proportions? Compare separate GHK-Cu, BPC-157, TB-500 and KPV listings. Need only BPC-157 and TB-500? The two-component blend lists 5 mg of each, not the four-component KLOW formula.
