Summary
GLOW is a supplier name for a three-part vial of GHK-Cu, BPC-157 and TB-500, marketed for skin and tissue repair. Ratios differ between suppliers, with GHK-Cu usually the largest component. Each part has its own research history; the combination has none.
Components
- Copper-binding tripeptide GHK-Cu GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva and urine. Early human data
- Synthetic pentadecapeptide BPC-157 BPC-157 is a synthetic 15-amino-acid peptide studied mainly for tendon, ligament, muscle and gut healing in rodents. Animal studies
- Thymosin beta-4 peptide TB-500 TB-500 is the trade name for synthetic thymosin beta-4 or its active fragment. Early human data
How it works
Suppliers pair a copper peptide studied in skin remodelling with two peptides studied in wound and tendon repair models.
Research use cases
Areas where GLOW blend has been studied. Inclusion here does not mean it works for that purpose.

What the research found
No combination studies
We found no published peer-reviewed study testing this exact combination in animals or people. Evidence comes only from studies of each component on its own.
Safety and open questions
Combining compounds can change how each behaves, and fixed ratios mean you cannot adjust one without the other. Component purity and identity are harder to verify in a blend, because a single certificate of analysis must confirm several peptides.
Regulatory status
Not approved. A supplier-defined combination; no regulator has evaluated it.

GLOW blend: common questions
How do I calculate amounts for a blend?
All components dissolve into the same water, so every draw contains them in the same ratio as the vial. Use the blend calculator, which shows the amount of each component per draw.
Why is my GLOW blend blue?
GHK-Cu gives a blue colour from its bound copper. A colourless solution may mean the copper peptide is missing or degraded.
Is GLOW blend approved for human use?
Not approved. A supplier-defined combination; no regulator has evaluated it.
