Quick Summary
Preclinical — blend not studiedGlow Blend combines three separately studied peptides in one vial: BPC-157, a 15-amino-acid gastric-derived peptide; TB-500, an acetylated fragment of thymosin β4; and GHK-Cu, a copper-binding tripeptide found in human plasma. Each has been studied mostly in cell and animal models. None is an approved drug, and the three-way blend has no published research.

Why Researchers Study It
- BPC-157 in rodent models of tendon, ligament and muscle injury
- Whether the TB-500 fragment shares activities of full-length thymosin β4
- GHK-Cu and collagen production by cultured fibroblasts
- Shared tissue-repair themes, the reason the three are grouped; the combination itself is untested
What It Is
Glow Blend is a product name for a mixture of BPC-157, TB-500 and GHK-Cu in a single vial.
Glow Blend is a product name for a mixture of BPC-157, TB-500 and GHK-Cu in a single vial. It is not a compound with its own scientific literature.
BPC-157 is a 15-amino-acid peptide taken from a protein isolated from human gastric juice. TB-500 is the acetylated 17–23 fragment of thymosin β4 (Ac-LKKTETQ), which is not the same as the full protein. GHK-Cu is the copper(II) complex of the plasma tripeptide Gly-His-Lys.
BPC-157 appears mainly in rodent models of tendon, muscle and gut injury. TB-500 has almost no direct data; most tissue-repair research concerns full-length thymosin β4. GHK-Cu has been studied in fibroblast cultures, animal wounds and topical cosmetic products.
The only published study combining any two of them is a 2026 rat Achilles-tendon study of BPC-157 and TB-500, which found no added benefit from combining them. No study of all three together was identified.
How It Works
3 established · 4 proposed or under investigation
Established
- GHK-Cu is a copper complex of the tripeptide GHK, which occurs naturally in human plasma
- TB-500 is chemically characterized as the acetylated 17–23 fragment of thymosin β4
- No mechanism has been established for this blend
Proposed / under investigation
- BPC-157: cell and rodent studies link it to fibroblast migration and blood-vessel growth pathways
- TB-500: in a cell study cited by FDA, the intact fragment did not significantly speed wound closure
- GHK-Cu: increased collagen synthesis in fibroblast cultures and broad gene-expression changes
- Whether the three interact in any way has not been studied
Research Status & Evidence
Preclinical — blend not studied
The evidence belongs to the individual ingredients: mostly cell and animal studies, a few small human studies of BPC-157 and topical GHK-Cu, and no human data for TB-500.
Types of evidence
- Available: Cell & lab studies
- Available: Animal studies
- Available: Early human studies
- Not available: Clinical trials
- Not available: Approved medical use
The evidence belongs to the individual ingredients, not the blend, and is mostly cell and animal work. FDA found five small human studies of BPC-157 and no human data for TB-500; human GHK-Cu data come mainly from topical cosmetic products. The only combination data are one rat tendon study of BPC-157 with TB-500.

Limitations
- No published research has studied this three-peptide blend or its ratios
- None of the three ingredients is an FDA-approved drug
- FDA's 2026 briefings weighed against adding BPC-157 or TB-500 to the 503A bulks list; FDA's compounding safety-risk page notes possible immunogenicity for all three
- BPC-157 and TB-500 are prohibited in sport under the WADA 2026 Prohibited List

Frequently Asked Questions
What is in the Glow Blend?

How is Glow different from Klow?
Klow contains the same three peptides plus a fourth, KPV, in an 80 mg vial. Glow has no KPV. Each component is also sold on its own: BPC-157, TB-500, GHK-Cu and KPV.
