Combination research blend
KLOW is a four-part research blend — GHK-Cu, BPC-157, TB-500 and KPV — combined in a single vial. It extends the GLOW concept with the addition of KPV, a tripeptide studied in inflammation research.
Each kit is 10 identical vials. Minimum 1 kit (10 vials) to the EU · 3 kits (30 vials) to the US. Free EU shipping.
Plain, unbranded packaging. No product names, no logos — nothing on the outside indicating what is inside. Tracked to a DPD Locker or your address.
For laboratory and in vitro research use only. Not for human or veterinary use, and not for use in diagnostic procedures.
KLOW builds on the three-peptide GLOW blend by adding KPV, the C-terminal tripeptide of α-MSH studied in inflammation research. All four peptides are presented together in one lyophilized vial; the 80 mg figure is the combined peptide mass per vial.
RetaNord supplies KLOW as a fixed kit of 10 lyophilized vials, each verified at 99%+ identity purity by HPLC with identity confirmed by mass spectrometry. Supplied for laboratory and in vitro research use only.
