Klow(TB+BPC-157+GHK+KPV) · 80mg（10mg/10mg/50mg/10mg）
Klow is a four-peptide research blend combining TB-500, BPC-157, GHK-Cu and KPV in a single 80 mg presentation. It is used where a study design calls for several repair-associated pathways to be examined together rather than in isolation.

- Combines angiogenic, anti-inflammatory and collagen-associated peptides
- Supplied as a single lyophilised 80 mg pen

Sold strictly for in-vitro laboratory research. Not for human or veterinary consumption.
What is in the blend
TB-500 is a synthetic fragment related to thymosin beta-4, studied for cell migration and angiogenesis. BPC-157 is a pentadecapeptide derived from a gastric protein sequence, examined widely in soft-tissue and gastrointestinal repair models.
GHK-Cu is a copper-binding tripeptide associated with collagen and elastin synthesis and antioxidant gene expression. KPV is a tripeptide fragment of alpha-MSH investigated for its anti-inflammatory signalling.
Why blends are studied
Tissue repair is not a single pathway. Combination formulations let researchers observe whether angiogenic, anti-inflammatory and matrix-building signals produce additive or interfering effects when present at the same time — something that cannot be assessed by running each compound separately.
Handling and storage
Lyophilised material is stable for extended periods when kept sealed, dry, and away from light. Long-term storage in research settings is commonly at -20°C, with short transit at ambient temperature considered acceptable for lyophilised powders.
Once reconstituted, solutions are refrigerated at 2-8°C and used within a limited window, as peptides in aqueous solution degrade far faster than in powder form. Repeated freeze-thaw cycles are avoided.
Reconstitution notes
Peptides in this catalogue are supplied lyophilised. In laboratory settings they are typically reconstituted with bacteriostatic or sterile water added slowly down the inside wall of the vial, never injected directly onto the powder pellet.
The vial is then left to dissolve on its own, or swirled gently. Vigorous shaking is avoided because mechanical shear can denature peptide chains and reduce measurable potency in subsequent assays.
Purity and batch testing
Every batch we list is accompanied by third-party analytical testing. The Certificate of Analysis linked on this page shows the lot number, HPLC purity trace, and mass spectrometry identity confirmation for the exact batch held in stock.
Purity figures quoted on this page are taken directly from that report rather than from a manufacturer datasheet, so what you read here matches the vial that ships.
Frequently asked questions
- Is this product for human consumption?
- No. Everything in the Fox Peptides catalogue is supplied strictly for in-vitro laboratory research use. It is not a medicine and is not for human or veterinary consumption.
- Do you provide a Certificate of Analysis?
- Yes. Each batch is third-party tested and the Certificate of Analysis for the lot currently in stock is linked directly on this page, showing HPLC purity and mass spectrometry identity confirmation.
- Where do you ship and how long does delivery take?
- We ship across the UK with tracked delivery. Orders are dispatched from the UK once payment clears, so there are no customs delays for UK customers.
- How do I pay?
- Checkout uses secure open-banking bank transfer. You approve the payment inside your own banking app, and your order is confirmed automatically once the transfer clears.
