What the GLOW blend is
GLOW is a research-market name for a vial combining BPC-157, TB-500 and GHK-Cu. It takes the Wolverine pairing and adds GHK-Cu, the copper tripeptide with the largest body of human skin data of any peptide sold for research, although that data is for creams, not vials. The name refers to the skin literature on GHK-Cu; it is not a claim about the blend.
What the research found
Each component has its own guide. GHK-Cu has small human trials of topical creams reporting improved skin firmness and wound healing, and cell-culture gene expression data; no injected human trial. BPC-157 and TB-500 have rodent repair data and, for TB-500, human data on the parent protein.
The combination. No published study tests the three together, or GHK-Cu with either of the others. GHK-Cu also has a chemistry point that matters for a blend: the copper ion can interact with other peptides in solution, so a reconstituted GLOW vial should be treated as a short-lived preparation and the certificate should confirm each component separately.
Stability, storage and handling
Keep unopened vials at 2 to 8 degrees Celsius, away from light; the GHK-Cu component is sensitive to chelating agents and the BPC-157 and TB-500 components degrade in solution over days to weeks. For a blend the certificate should show identity and purity for each peptide.
Legal status in the UK, 2026
None of the three is a controlled substance under the Misuse of Drugs Act 1971. The blend is not a licensed medicine and cannot be sold or advertised for human use in the UK; supplied strictly for laboratory research. In sport BPC-157 falls under WADA S0 and TB-500 under S2.
What to check before buying
Milligrams of each of the three peptides per vial, HPLC purity and mass spectrometry identity for each, a batch number matching the certificate, and cold-chain shipping. Every Origin Peptides batch is independently tested and its certificate of analysis is published on the product page and the Lab Testing page.
Frequently asked questions
What is in the GLOW blend?
BPC-157, TB-500 and GHK-Cu in one vial.
Is there a study of the three together?
No.
Why is the powder blue?
The copper in GHK-Cu. A colourless GLOW vial is a warning sign.
How does GLOW differ from KLOW?
KLOW adds KPV, an alpha-MSH fragment from the inflammation literature.
Is it legal in the UK?
Legal to buy and possess as a research compound; not lawful to sell or advertise for human consumption; two of the three components banned in sport.
