PTY-GLW blend
Three peptides in one vial: GHK-Cu, BPC-157 and TB-500. Published studies look at each of them alone, so the notes below describe the individual ingredients and make no statement about the trio acting together.
- Container
- Glass vial, crimp seal, flip-top cap
- Storage
- -20 °C, desiccated, protect from light
- In the vial
- GHK-Cu 50 mg + BPC-157 10 mg + TB-500 10 mg
- Paperwork
- Lot certificate (HPLC + mass spec) shown before you pay

What researchers study it for
- Wound closure in animal skin
- Production of collagen and other matrix proteins
- Animal models of tendon, ligament and muscle damage
- Bone repair in animals
- Detection methods and breakdown products for drug testing
How it is thought to work
GHK-Cu: GHK holds copper(II), and researchers have suggested the copper-bound version is the one that acts in experiments. BPC-157: Nobody has pinned down how it acts. TB-500: The parent molecule, thymosin beta-4, is a 43-residue protein that holds onto actin.
Where the research stands
Blend of research compounds. Each component is studied separately; as a combined vial it has no dedicated published research. The least-established component is GHK-Cu: mostly lab and animal findings.
