In DSS colitis and CD45RB-high transfer colitis in mice, KPV produced earlier recovery, significantly stronger regain of body weight, and significantly reduced inflammatory infiltrate and colonic myeloperoxidase activity.

premium-grade research peptides
Klow80 mg
Four peptide regenerative blend: GHK-Cu + TB-500 + BPC-157 + KPV. Lyophilized powder for reconstitution.
What it is
Klow is a four-peptide blend of GHK-Cu, TB-500, BPC-157, and KPV in a single lyophilized vial. It adds KPV, a lysine-proline-valine tripeptide derived from alpha-melanocyte-stimulating hormone, to the three-peptide GHK-Cu, TB-500, and BPC-157 combination. Each constituent has its own separate literature, and the blend itself has not been studied.

How it works
Klow combines four regenerative peptides studied across skin, tissue repair and inflammation research.
GHK-Cu
The copper signal
GHK-Cu is a copper tripeptide researched for collagen support and skin remodelling.
Repair pair
BPC-157 plus TB-500
BPC-157 is studied for tissue repair while TB-500 is researched for cell migration, the two classic recovery pathways.
KPV
The inflammation side
KPV adds the anti-inflammatory tripeptide, extending the blend toward gut and inflammatory models.
Key benefits
- Recovery research covering skin, soft tissue, and gut support.
- All-in-one recovery protocols combining four studied peptides in one vial.
- Studied as a broader recovery option than the three-peptide blend.
Laboratory research only. Not for human or veterinary use.
What published research is studying
Preclinical research- Skin remodelling and wound repair (GHK-Cu)
- Dermal and corneal repair in animal models and Phase 2 trials (thymosin beta-4)
- Tendon and ligament healing in rodent injury models (BPC-157)
- Intestinal inflammation in mouse colitis models (KPV)
No published research has examined this four-peptide combination. KPV and BPC-157 evidence is entirely preclinical, GHK-Cu human studies are small, and human trials exist only for full-length thymosin beta-4.
Key research findings and references
Key research findings
In rabbit full-thickness open wounds, topical tripeptide-copper complex produced a significantly smaller mean unhealed wound area than untreated controls at days 7, 14, and 21.
Cangul IT et al., Vet Dermatol 2006In a 56-day Phase 2 trial in 9 patients with severe dry eye, the thymosin beta-4 group showed a 35.1% greater reduction in ocular discomfort and a 59.1% greater reduction in corneal fluorescein staining than vehicle at day 56.
Sosne G et al., Cornea 2015In cultured rat tendon fibroblasts, BPC-157 accelerated outgrowth from tendon explants, increased survival under oxidative stress, and raised migration, with dose-dependent FAK and paxillin phosphorylation.

Research handling
Full handling guide- 01
Lyophilized, sealed, batch-numbered
Each vial ships as a freeze-dried powder under an inert seal, tied to the batch on its Certificate of Analysis.
- 02
Store cold and dark
Unopened vials are kept refrigerated at 2-8°C away from light. Reconstituted material is stored refrigerated and used within the window the research plan defines.
- 03
Reconstitute with bacteriostatic water
The included bacteriostatic water is added slowly down the vial wall and the vial is swirled, never shaken.
- 04
Research use only
Supplied for laboratory research. Not for human or veterinary use. Handle with the personal protective equipment the laboratory requires.
