GLOW blend (BPC-157, GHK-Cu, TB-500)
Cosmetic & dermatologic
Evidence level
Anecdotal evidence
Approval status
Not approved
Mechanism of action
- 1.GHK-Cu is studied in laboratory models for stimulating collagen and glycosaminoglycan synthesis and for delivering copper to healing tissue.
- 2.BPC-157 is proposed to support blood-vessel formation in animal wound models.
- 3.TB-500 is studied for actin dynamics and cell migration in animal repair models.
- 4.The blend assumes that copper-driven collagen production plus better blood supply and cell migration together improve skin.
- 5.No study has measured that in people.
Studied for
- Skin quality, scarring and hair claims
- Wound and post-procedure recovery
- Collagen production in laboratory studies
- None of the combination claims has been tested
Reported effects
- Skin appears firmer in user accounts
- Laboratory increases in collagen markers for GHK-Cu alone
- No controlled human outcomes for the blend
Side effects
- Injection-site reactions
- Possible copper excess with high-dose GHK-Cu
- Headache and nausea
- Unknown long-term effects of the combination
Research protocol
Research context only — no human protocol exists. Vendors describe 10 syringe units daily from a vial reconstituted in 3 ml, which depends entirely on the concentration of that specific vial. The GHK-Cu component is often paired with zinc in community practice, which is not a validated requirement.
Research context only
Evidence justification
The ingredients have laboratory and animal data only, the combined product has never been studied, and no regulator has approved any component for these uses.
