KLOW Blend

Transparency note on composition: "KLOW" is a research-blend name used across the peptide-research industry, but the letter mapping is not formalized by any standards body. After surveying multiple supplier descriptions, the most widely used interpretation - and the one we adopt here - is K = KPV, L = BPC-157 (a Lys-stabilized fragment derived from gastric BPC), O = GHK-Cu, W = TB-500. The total standard mass is typically 80 mg per vial. Our COA discloses the exact per-component mass for every batch so researchers can verify the composition directly rather than relying on the name.

No. KLOW Blend is not an approved drug product and is not intended for human or veterinary use. It is supplied as a research-grade reagent for in vitro investigation only. None of the four constituent peptides hold FDA approval as a finished pharmaceutical in this combination.

Each peptide in KLOW maps to a distinct mechanistic axis (NF-kappaB, VEGF/NO, copper-ECM, actin-thymosin). Researchers studying convergent inflammation-repair pathways often need to expose cell or tissue models to all four simultaneously. A co-lyophilized blend reduces pipetting variance, single-component degradation differences, and reconstitution-step contamination risk in multi-peptide experiments.

Each individual peptide is HPLC- and mass spec-tested to ≥99% purity before blending. Post-blend, the lyophilized matrix is re-screened by HPLC to confirm that all four peaks are present at the expected relative ratios. The COA documents both single-component and post-blend results.

KLOW is intended as a fixed-ratio combinatorial reagent, not as a source of isolated single components. Researchers needing per-peptide dose-response curves should source KPV, BPC-157, GHK-Cu, and TB-500 individually. KLOW is most useful when the experimental question concerns the combined matrix rather than any one constituent.

Lyophilized KLOW should be stored at -20°C for long-term stability. Reconstitution is typically performed with bacteriostatic water; once reconstituted, store at 2-8°C and used within 14 days. Avoid repeated freeze-thaw cycles and protect from light. The copper-binding GHK component is sensitive to strongly reducing or chelating buffers.
