GLOW is a three-peptide research blend that combines GHK-Cu, BPC-157, and TB-500 in a single lyophilized vial. It’s one of the most-studied regenerative peptide combinations, pairing a copper tripeptide with two tissue-repair peptides for research into skin remodeling, wound repair, and vascular formation.
What’s in the blend, and why three
Each component targets a complementary pathway in tissue-repair research:
- GHK-Cu (copper tripeptide) — studied for collagen and matrix synthesis, angiogenesis, and gene-expression modulation.
- BPC-157 (Body Protection Compound, a gastric pentadecapeptide) — studied for cytoprotection and angiogenic / nitric-oxide signaling.
- TB-500 (a Thymosin Beta-4 fragment) — studied for actin regulation and cell migration.
Combining collagen/matrix activity (GHK-Cu), cytoprotective signaling (BPC-157), and cell motility (TB-500) lets researchers study additive or synergistic effects on tissue repair in a single model.
GLOW vs KLOW
GLOW is the three-peptide base. [KLOW »] adds a fourth peptide — KPV — for an anti-inflammatory dimension. If your research also involves inflammation or cytokine modulation, KLOW is the four-part extension of this blend.
Research context
This is a research-grade blend supplied for in-vitro and laboratory study only. All three components are investigational and not FDA-approved. For full mechanism and literature, see our BPC-157 Research Overview », GHK-Cu Research Overview », and TB-500 Research Overview ». The individual peptides are also available on their own: GHK-Cu », BPC-157 », TB-500 ». For the two-peptide BPC-157 + TB-500 pair without the copper component, see Wolverine ».
Composition (typical — adjust to your vial spec)
70 mg total lyophilized blend per vial — GHK-Cu 50 mg · BPC-157 10 mg · TB-500 10 mg.

Laboratory handling
Copper complexes are light-sensitive. Store lyophilized material cold and protected from light (long-term at −20 °C). After reconstitution, refrigerate at 2–8 °C, protect from light, avoid repeated freeze–thaw cycles, and use within your protocol window. Confirm identity and purity against the batch COA before use.
Research FAQ
What is GLOW? A three-peptide research blend — GHK-Cu, BPC-157, and TB-500 — studied for tissue repair, skin remodeling, and vascular formation.
How is GLOW different from KLOW? KLOW adds a fourth peptide, KPV, for an anti-inflammatory dimension; GLOW is the three-peptide base.
Why does the powder have a blue tint? The GHK-Cu component is copper-bound, which gives the lyophilized blend a characteristic light blue color — expected, not a defect.
