Frequently Asked Questions

What is KLOW?
KLOW is a research blend composed of four distinct peptides - BPC-157, GHK-Cu, TB-500, and KPV - combined in lyophilized form for in vitro laboratory study. Because it is a physical combination of separate molecules rather than a single compound, KLOW does not have one molecular formula, molecular weight, or CAS number. Pure Health Peptides supplies it strictly for in vitro laboratory research.
What is in the KLOW blend?
KLOW combines four separately characterized research peptides: BPC-157, a 15-amino-acid partial sequence of a gastric protein (C62H98N16O22); GHK-Cu, the copper-binding tripeptide Gly-His-Lys (C14H24N6O4) in complex with copper, approximately 403.9 g/mol; TB-500, full-length thymosin beta-4, a 43-amino-acid actin-binding peptide; and KPV, the tripeptide Lys-Pro-Val. Each is a distinct structural class, which is where the name KLOW comes from.
Why doesn't KLOW have a single molecular formula?
KLOW is a blend of four different molecules rather than one compound, so it cannot be described by a single molecular formula, molecular weight, or CAS number. Each component has its own chemical identity, and analytical testing is carried out on the individual peptides and on the blended material per lot. Representative values reported on a Certificate of Analysis apply to that specific tested material.
What are the components of KLOW studied for in research?
In controlled laboratory settings, each component is studied separately. Research literature reports BPC-157 as a partial gastric-protein sequence examined in tissue-culture study models; GHK-Cu as a copper-binding tripeptide examined in models of extracellular-matrix gene expression; thymosin beta-4 (TB-500) as an actin-binding peptide examined in cell-motility models; and KPV as a tripeptide examined in models of cellular signaling. These are research findings; all applications are non-clinical.
What size does KLOW come in, and is it third-party tested?
KLOW is supplied as a lyophilized blend of the four components (BPC-157, GHK-Cu, TB-500, and KPV). Because it is a multi-component blend, purity is reported per lot on the Certificate of Analysis rather than as a single fixed figure. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification. Store in a cool, dry place away from light and moisture, and consult the Safety Data Sheet before handling.
Is KLOW intended for human or clinical use?
No. KLOW is for research use only and is not intended for human or veterinary use. It has not been evaluated by the FDA and is not a drug, food, cosmetic, or dietary supplement. It is supplied only to qualified research professionals for in vitro laboratory research, and KYC verification is required prior to fulfillment. Any use outside of controlled in vitro research is strictly prohibited.
