Klow Blend

Klow Blend is supplied as a laboratory research reference material for in-vitro and laboratory research use only. Cataloged under SKU Klow-Blend, this four-component lyophilizate combines BPC-157, TB-500, GHK-Cu, and KPV in a single vial, presenting as a white to off-white lyophilized powder intended for analytical characterization, comparative peptide chemistry studies, and reference-standard applications in controlled laboratory settings.

The composition brings together four structurally distinct synthetic peptides. BPC-157 is a 15-residue pentadecapeptide fragment sequence (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) originally described from a gastric protein context. TB-500 corresponds to the 17-residue active fragment sequence associated with the thymosin beta-4 family. GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine presented as its copper(II) chelate, a well-characterized metallopeptide complex with a defined 1:1 copper coordination geometry through the histidine imidazole and adjacent nitrogen donors. KPV is the C-terminal tripeptide lysine-proline-valine, a low-molecular-weight sequence frequently used in comparative small-peptide analytical work. Each constituent contributes a distinct mass, chromatographic retention profile, and UV signature, making Klow Blend a useful multi-analyte reference material for method development and orthogonal identity confirmation.

Klow Blend is manufactured by solid-phase peptide synthesis and finished by lyophilization to a dry, free-flowing powder suitable for reconstitution in laboratory diluents for analytical workflows such as HPLC, LC-MS, UV spectrophotometry, and peptide mapping. Purity is specified as not less than 98% by HPLC on a per-component basis, with identity, appearance, and lot-specific analytical results documented on the Certificate of Analysis issued for each production lot and available on request. Formulators and analytical chemists should note that the copper-chelated GHK-Cu component imparts a characteristic blue tint upon reconstitution and requires attention to buffer selection, pH range, and avoidance of strong reducing or chelating agents that can perturb the copper coordination sphere.

Published scientific literature has examined Klow Blend and its individual constituents in preclinical research contexts, and this catalog entry references that body of literature for characterization purposes only. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding Klow Blend and provides no administration or dosing guidance. This material is not a drug, supplement, cosmetic, or food, and is not for human or veterinary use, injection, or ingestion. For long-term stability, store the lyophilized Klow Blend powder sealed, protected from light and moisture, at the temperature indicated on the lot-specific Certificate of Analysis, which remains the sole authoritative source for identity and purity data.
