What is KLOW?

KLOW combines the copper tripeptide GHK-Cu with BPC-157, TB-500 and KPV in a single 80mg vial, extending the GLOW blend with KPV's anti-inflammatory research profile.\n\nEach vial is produced by solid-phase synthesis, purified by reverse-phase HPLC and verified by mass spectrometry before release. Purity and identity for all four components are published on the certificate of analysis.

KLOW reconstitution reference

Reconstitute with bacteriostatic water. The table shows the concentration and syringe volume produced by common dilutions of a 10mg vial, for reference when preparing research stock solutions.
