Description
What it is
KLOW is a co-formulated research blend of four separate peptides lyophilised together in one vial: GHK-Cu (copper tripeptide-1, roughly 401.9 g/mol), BPC-157 (C62H98N16O22, about 1419.5 g/mol), TB-500 (a Thymosin beta-4 fragment near 889 g/mol or the full protein near 4963 g/mol) and KPV (Lys-Pro-Val, C16H30N4O4, about 342.4 g/mol). KLOW is GLOW with KPV added, supplied here as an 80 mg total fill. It is a defined mixture, not a single molecule.
Research context
Each component has its own separate research literature: GHK-Cu as a copper-binding matrix tripeptide, BPC-157 in preclinical tissue-repair models, TB-500 as an actin-sequestering cell-migration peptide, and KPV as an anti-inflammatory alpha-MSH fragment studied at the NF-kB pathway. There is no blend-specific study data, and combining peptides does not transfer or multiply their individual findings. This listing describes the constituent molecules for laboratory investigation only and makes no claim of synergy or of any effect in humans or animals.
Handling and storage
Supplied lyophilised for reconstitution with bacteriostatic water as a research-handling step. Store cold and protected from light; reconstituted material is cold-chain dependent. Four peptides with different degradation profiles share one vial, so finished-blend stability is the relevant reference.
Testing and quality
Every batch is third-party tested. The Certificate of Analysis resolves all four components separately by identity (sequence and mass spectrometry, keyed to the Lys-Pro-Val sequence for KPV) and load (mg), with copper-complexation confirmation for GHK-Cu.
Supplied for laboratory research use only. Not for human or animal consumption.
