The KLOW Blend brings together four peptides that each have their own body of research: the copper peptide GHK-Cu, BPC-157, TB-500 and the α-MSH fragment KPV. Supplying them together keeps the ratio identical from vial to vial.
GHK-Cu is studied in skin-remodelling and collagen research, BPC-157 and TB-500 in tissue-repair and cell-migration models, and KPV in inflammation and gut-lining research. Each Monark vial holds 80mg of lyophilized blend, tested by an independent laboratory.
Every batch is tested for purity by an independent laboratory, and the results are recorded on a certificate of analysis (COA).

All Monark products are sold for laboratory research use only. Not for human or veterinary use. Not intended to diagnose, treat, cure or prevent any disease.

The blend
Each peptide in KLOW is studied through a different pathway: GHK-Cu in copper-dependent matrix and collagen signalling, BPC-157 in growth-factor and blood-vessel signalling, TB-500 in actin binding and cell movement, and KPV in inflammatory signalling.
Combining them at a fixed ratio makes it simpler to run consistent, repeatable comparisons across a study, without weighing out four separate compounds.
In the literature
GHK-Cu is studied in research on skin remodelling and collagen synthesis.
BPC-157 and TB-500 are explored in preclinical models of soft-tissue repair and cell migration.
KPV is investigated in laboratory models of inflammatory signalling and the gut lining.

Each 80mg vial contains GHK-Cu 50mg, BPC-157 10mg, TB-500 10mg and KPV 10mg, supplied together as one lyophilized powder.
The copper in GHK-Cu gives the blend a light blue tint. It's normal and expected.
Yes. GHK-Cu, BPC-157, TB-500 and KPV are all available on their own if your research needs a different ratio.
