GLOW is a vendor name for BPC-157 and TB-500 together in one vial. Both are studied in tissue-repair models and are often sold side by side, so blending them is a convenience, not a new molecule.
There is no published study of the two together. This entry exists because people search for the name; the science is in the two component entries and in the BPC-157 vs TB-500 comparison.

What is in it
A blend is a mixture of separate peptides in one vial. The name is a vendor label, not a chemical name, and the ratio varies between suppliers. The table lists each component and links to its own entry, where the identity data and references live.
| Component | Residues | Avg mass | Entry | What the studies measured | WADA |
|---|---|---|---|---|---|
| BPC-157 | 15 | 1419.5 g/mol | 0001 | Gut, tendon, muscle and vessel models in rats; a few small human reports | S0, prohibited |
| TB-500 | 7 | 889.0 g/mol | 0002 | Mostly studies of the parent protein thymosin beta-4; detection work on the fragment | S2.3, prohibited |
At Peptidarium, GLOW is BPC-157 (10 mg) and TB-500 (5 mg) in one vial. Some suppliers sell a three-peptide version with GHK-Cu under the same name; check the label. Our certificate reports purity and identity for each peptide separately.
What the studies measured
There is no published study of GLOW as a mixture. Everything known comes from studies of the components on their own, almost all in animals or cells. The rows below summarise those entries; the evidence for each is in its own entry.
| Component | Model | Main lines of research | Human data |
|---|---|---|---|
| BPC-157 | Rats, cell cultures | Gut, tendon, muscle and vessel repair | A few small uncontrolled reports |
| TB-500 | Mostly the parent protein, thymosin beta-4 | Wound, heart and eye repair for the protein; detection for the fragment | None for the fragment |
Regulatory and sport status
As of this revision. General information, not legal advice.
| Where | Status |
|---|---|
| UK, EU, US | No component is a licensed medicine. None is a controlled drug in the UK. May not be supplied or promoted for human use. |
| Sport | Both components are prohibited at all times: BPC-157 under class S0 and TB-500 under class S2.3. A blend containing them is prohibited.2 |
Open questions
- Whether the components interact at all. No study has tested them together, so any claim about the mixture rests on separate studies.
- How a certificate should read for a blend: purity by HPLC gives one peak per peptide, and identity by mass spectrometry must confirm each one. Ask any supplier for all of them.
- The ratio. Different suppliers use different amounts of each peptide under the same name.
Common questions
What is in GLOW?
At Peptidarium, BPC-157 10 mg and TB-500 5 mg in one vial. Some suppliers add GHK-Cu under the same name, so check the label.
Has GLOW been studied?
No. There is no published study of the mixture. Each component has its own literature, almost all in animals or cells.
Is GLOW banned in sport?
Yes, in effect. BPC-157 and TB-500 are both prohibited at all times.
What should a GLOW certificate show?
One HPLC purity figure and one mass spectrometry identity check for each of the two peptides, not a single number for the vial.
