KLOW Blend 80mg overview
KLOW Blend 80mg (blend — no single CAS number) combines four synthetic peptides in one lyophilized vial: 10mg BPC-157, 50mg GHK-Cu, 10mg TB-500, and 10mg KPV. NexPept supplies it as a lyophilized research reference standard for in vitro cellular signalling, peptide-ion interaction, and structural/cytoskeletal research. Not for use in any living organism.
Every lot is independently tested by a third-party analytical laboratory before it is listed. The Certificate of Analysis reports HPLC purity, mass spectrometry identity confirmation, and net-content verification, and stays published in our COA library after the batch sells out.

Research context
This four-peptide blend is used as a combined tool set in preclinical in vitro settings. Published work on its components has examined cellular signalling models, peptide–ion interaction studies involving the copper-binding component, structural and cytoskeletal research applications, and molecular interaction assays, letting researchers probe several overlapping research pathways from a single vial.
NexPept supplies BPC-157, GHK-Cu, TB-500, and KPV pre-combined at a fixed 10mg/50mg/10mg/10mg ratio rather than as a custom mix, so every vial reflects the same proportion from lot to lot. Researchers who need to vary any one component independently typically use the single-compound vials instead.
This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.

Frequently asked questions
What testing does each batch go through?
Identity and purity are confirmed by high-performance liquid chromatography and mass spectrometry before a lot is listed. The current lot, KLOW-80MG-B01, tested at 99.75% on May 8, 2026. If a lot has not been tested, it does not go on sale.
What class of compound is KLOW Blend?
A four-peptide research blend combining BPC-157, GHK-Cu, TB-500, and KPV. It is supplied as a lyophilized powder and handled as a peptide reference standard, not as a formulation.
How does KLOW Blend differ from Glow Blend?
KLOW Blend adds a fourth peptide, KPV, on top of the three components (GHK-Cu, BPC-157, TB-500) found in Glow Blend, bringing total net content to 80mg instead of 70mg. Researchers choose between the two based on which combination of components their protocol calls for.
What physical form does it arrive in?
A blue lyophilized (freeze-dried) solid — the color comes from the copper-bound GHK-Cu component — sealed in a single vial. Net quantity is 80mg total across the four peptides. No preparation, reconstitution or handling instructions are supplied; those are determined by qualified personnel under your own institutional protocols.
