A blend described by its maker and by the separate records of three of its four components.
KLOW is a research blend Peptara Labs supplies in one vial: BPC-157, TB-500, GHK-Cu and KPV. BPC-157 is a pentadecapeptide first isolated from human gastric juice, TB-500 is described in a registered trial as a fragment of thymosin beta-4, and GHK-Cu is the copper complex of a naturally occurring tripeptide.

KLOW has no approved human use, and neither does any of its four components. Peptara Labs sells it as research-grade material.

This guide’s research record covers BPC-157, TB-500 and GHK-Cu separately. It holds no study of the four-peptide blend and no entry for KPV, so nothing on this page describes what the blend does.
The blend has no registered study on this record. The components are covered on the BPC-157 and GHK-Cu pages, and TB-500 appears in one registered trial, NCT07487363.

One lot and one purity figure cover four compounds. No second-laboratory report is listed for KLW-260412-A on the pages this guide read on 14 September 2026. The points to read on the certificate are what it reports for each compound, and how it identifies KPV, which has no entry in this guide’s research record.

A four-compound vial turns the usual checks into six. In order:
Lot KLW-260412-A, at 98.60% HPLC purity on certificate COA-2026-8537, tested in June 2026 by Titreon Analytical.
Four peptides in one vial: BPC-157, TB-500, GHK-Cu and KPV, by Peptara Labs’ own description.
No. None of its four compounds has an approved human use, and Peptara Labs sells KLOW as research-grade material.
The published record shows one lot and one purity figure for the blend. Read what the certificate reports for each compound before you rely on it; it opens on titreonanalytical.com with the key printed on it.
