PeptideCompareKLOW Blend — GLOW, plus an anti-inflammatory layer.
KLOW Blend is the four-peptide sibling of GLOW: the same GHK-Cu + BPC-157 + TB-500 base with KPV added, bringing the total to 80mg per vial. KPV is the component suppliers point to when framing the product around inflammation-sensitive research rather than tissue repair alone.
What KPV adds
KPV (Lysine-Proline-Valine) is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH). Despite its small size it is studied for inhibiting NF-κB nuclear translocation — a master regulator of inflammatory gene expression — along with direct antimicrobial activity, without the melanogenic (pigmentation) effects of the parent hormone. Suppliers market KLOW over GLOW specifically for research questions where an inflammatory component is of interest alongside tissue repair and collagen support.
KLOW vs GLOW — which one suppliers list
Not every supplier carries both. Some stock only GLOW (the 3-peptide, 70mg version), some only KLOW, and a few stock both side by side at a roughly €10-20 premium for KLOW. If a supplier you're comparing only lists one of the two, that generally reflects their actual catalogue rather than a data gap — check both guide pages and the comparison cards to see which EU vendors carry which.
Potency retained over time
Each line is one storage condition: it starts at 100% and falls as potency is lost. Above the dashed 80% line the material is considered reliable — hover for exact values.
