What is the Klow Stack?
5 min read · Updated May 2026
The Klow Stack is a four-peptide research formulation containing GHK-Cu (50mg), KPV (10mg), BPC-157 (10mg) and TB-500 (10mg) — 80mg total. Presenting four peptides with distinct mechanisms in one vial lets researchers investigate combined activity across multiple signalling pathways simultaneously, under standardised conditions.
Research use only. The Klow Stack is supplied strictly for in-vitro laboratory research. This page does not describe dosing, administration, or use in humans or animals, and makes no therapeutic claims.
The four components
- GHK-Cu — copper-peptide complex studied for copper-dependent signalling.
- KPV — α-MSH (11-13) tripeptide studied for melanocortin-linked and inflammatory signalling.
- BPC-157 — probe for peptide-mediated signalling mechanisms.
- TB-500 — thymosin beta-4 fragment studied for actin/cytoskeletal dynamics.
Why study them as a set
The four-peptide system supports exploration of convergent and parallel signalling across copper-dependent, melanocortin-linked and cytoskeletal pathways within one experimental matrix — and comparison of individual versus combined activity.
How it is supplied
Supplied as a vial with a Certificate of Analysis, stored refrigerated at 2–8°C. The components are available individually too.
