GLOW blend (BPC-157, GHK-Cu, TB-500)
A three-peptide skin-and-repair blend sold on collagen and healing claims that no trial has tested.
What it is
A prepackaged mixture of GHK-Cu with BPC-157 and TB-500, commonly 50 mg GHK-Cu with 10 mg each of the other two per vial, positioned as a skin, hair and healing stack. The combination has not been studied in humans and none of the components is an approved medicine.
How it works
- 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.
What it's studied for
Reported and studied effects
- Skin appears firmer in user accounts
- Laboratory increases in collagen markers for GHK-Cu alone
- No controlled human outcomes for the blend
Research protocol notes
Research context onlyResearch 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.
These figures are described so you can understand what researchers did. They are not a dose, a schedule, or a suggestion — and they are not a substitute for a doctor.
Possible side effects and contraindications
Safety profile
Possible side effects
- Injection-site reactions
- Possible copper excess with high-dose GHK-Cu
- Headache and nausea
- Unknown long-term effects of the combination
Contraindications and cautions
- Not established
- Copper-handling disorders such as Wilson's disease
- Cancer history
- Pregnancy, breastfeeding and childhood
- Prohibited in competitive sport
A side-effect list is never complete, and these are not the only situations that warrant caution. Anything unexpected, or anything you are unsure about, should be discussed with a doctor before use.
Evidence assessment
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.
