KLOW is UK Peptides' proprietary high-payload research blend combining KPV, GHK-Cu, BPC-157 and TB-500 in a single co-lyophilised vial. Designed to support extended in-vitro protocols investigating combined anti-inflammatory, copper-peptide collagen and connective-tissue repair pathways. Each component independently HPLC-verified to ≥98%.
The range
Every vial in the range is lyophilised, labelled and lot-numbered the same way, with the certificate for its lot linked from its own product page. Pictured: BPC-157, TB-500, GHK-Cu, Glow and Retatrutide.
Browse the rangeKLOW is UK Peptides' proprietary quad-peptide co-lyophilised research blend combining KPV (Lys-Pro-Val), GHK-Cu (copper tripeptide-1), BPC-157 (pentadecapeptide) and TB-500 (Thymosin Beta-4 fragment) in a single 80mg vial. Designed for research groups investigating combined anti-inflammatory, copper-peptide collagen and connective-tissue repair pathways. Every component is independently HPLC-verified to ≥98% purity with a batch-matched Certificate of Analysis.
Store the lyophilised vial at -20°C, sealed and protected from light — copper peptide components are particularly light-sensitive. Refrigerate the reconstituted solution at 2–8°C and use within 14 days.
For longer storage, aliquot and freeze at -20°C. Do not refreeze thawed material.
The KLOW Certificate of Analysis reports HPLC-UV purity and mass-spectrometry identity for each of the four component peptides separately. Every batch is signed off by an accredited independent laboratory, with copper content on the GHK-Cu component verified independently. The signed PDF CoA is supplied with every order.
Co-lyophilised multi-peptide blends demand more sophisticated HPLC method development than single-peptide vials — under-dosing or component substitution on the grey market is common. UK Peptides addresses this with four-component independent verification on every KLOW lot, UK stock, same-day Manchester dispatch and full lot traceability visible on this product page.
KLOW is a proprietary co-lyophilised research blend of four separately-studied peptides: KPV (Lys-Pro-Val, the C-terminal tripeptide of α-MSH), GHK-Cu (copper tripeptide-1), BPC-157 (a synthetic pentadecapeptide) and TB-500 (a fragment of Thymosin Beta-4). Each component is HPLC-verified independently.
