GLOW Peptide Blend — GHK-Cu, BPC-157 and TB-500
GLOW is a three-peptide research blend supplied as 70 mg of total peptide in one lyophilized vial. It combines GHK-Cu (a copper-binding tripeptide), BPC-157 (a 15-residue gastric-derived peptide) and TB-500 (a synthetic thymosin beta-4–derived peptide). The amount of each component in your lot is printed on its Certificate of Analysis.
What each component is studied for
- GHK-Cu — gene-expression and extracellular-matrix models (reviewed by Pickart & Margolina, Int J Mol Sci, 2018)
- BPC-157 — tendon-fibroblast outgrowth and migration in vitro (Chang et al., J Appl Physiol, 2011)
- TB-500 / thymosin beta-4 — actin binding and cell-migration models (reviewed by Goldstein et al., Expert Opin Biol Ther, 2012)
These findings come from specific cell and animal models of the individual peptides. They do not describe the blend, and they do not establish any outcome for the material supplied here.
GLOW vs KLOW
KLOW contains the same three peptides plus KPV (80 mg total). GLOW has no KPV (70 mg total). Each has its own page and lot-linked COA.
GLOW specifications
- Components: GHK-Cu, BPC-157, TB-500
- Total peptide per vial: 70 mg (per-component amounts on the lot COA)
- Component CAS numbers: GHK-Cu 89030-95-5 · BPC-157 137525-51-0
- Blend CAS / formula: none — a blend has no single CAS number or molecular formula
- Form: Blue to blue-violet lyophilized powder in a sealed glass vial (color from the copper in GHK-Cu)
- Storage: Sealed at −20 °C, dry and protected from light
Analytical considerations
Each component is identified separately by LC-MS against its theoretical mass, and purity is measured by reversed-phase HPLC. The lot-linked COA on this page reports the results for the material you receive.
Laboratory handling
Bring the closed vial to room temperature before opening, prepare solutions according to your laboratory's validated protocol, and record the lot number, concentration and storage conditions. Minimize repeated freeze–thaw cycles.
Common research questions
Why is the powder blue? GHK-Cu is a copper complex. The color comes from the copper and does not by itself indicate purity; check the lot COA.
Does PX1 offer GLOW in other formats? Yes. GLOW capsules are listed separately with their own page and documentation.

Research monograph
GLOW Blend — Complete Research Overview
What is the GLOW blend?
GLOW is a three-component research blend of GHK-Cu, BPC-157 and TB-500 supplied as a single lyophilized preparation. It is the most frequently requested combination in dermal and connective-tissue research models, where the copper tripeptide is studied alongside two peptides associated with cell migration and angiogenic signaling.
PX1 Research releases GLOW against component-level analytical data so the ratio and identity of each constituent are documented on the batch certificate.
Why the components are studied together
GHK-Cu is one of the most characterized copper-binding peptides in dermatology literature, reported to influence collagen I and III expression in fibroblast culture. TB-500 addresses actin dynamics and cell motility; BPC-157 contributes angiogenic and cytoprotective readouts.
Combining them in one vial removes cross-vial concentration error, which is a common confound when researchers prepare three separate solutions for the same well plate.
Laboratory handling and storage
GLOW ships as a lyophilized powder in a sealed, tamper-evident vial. Store the unopened vial between −20°C and −80°C, protected from light, until the day of use. In this state the peptide is stable through the labeled expiration date printed on the lot documentation.
Purity, testing and Certificate of Analysis
Every PX1 Research lot of each GLOW component is manufactured in the United States and released against a documented specification of ≥99% purity by reversed-phase HPLC, with identity confirmed on the same lot by high-resolution LC-MS against the theoretical mass of the sequence.
Research use only
The GLOW blend supplied by PX1 Research is intended strictly for in-vitro laboratory and research applications. It is not a drug, food, cosmetic, or medical device, and it is not for human or veterinary use, diagnosis, treatment, or consumption.
Researchers are responsible for handling the compound in accordance with their institution's safety procedures and all applicable local regulations. Safety data sheets and current lot documentation are available on this site.
What the three components contribute
GLOW is a three-component research blend of GHK-Cu, BPC-157 and TB-500 supplied together in a single lyophilized vial. The formulation exists because dermal and connective-tissue repair models typically require matrix remodeling, new vasculature and cell migration to be engaged in the same preparation, and those three descriptions map onto the three components respectively.
GHK-Cu is a copper-binding tripeptide described in the literature in connection with extracellular matrix turnover and fibroblast signaling. BPC-157 is a synthetic 15-mer studied for angiogenic and nitric-oxide-pathway signaling. TB-500 is the active fragment region of thymosin beta-4 and is described in terms of actin sequestration and cell motility.
Because the three differ in mass by an order of magnitude, the blend's behavior in solution is governed largely by its largest component while its chromatographic identification depends on resolving the smallest. That asymmetry is why blend certificates are reported per component rather than as a single figure.
Purity, identity and per-component certificate reporting
PX1 reports GLOW against a reversed-phase method with a gradient shallow enough to resolve the copper-complexed tripeptide, the 15-mer and the thymosin fragment as distinct peaks, with identity for each confirmed by LC-MS against its theoretical mass. A blend reported as a single purity number cannot demonstrate that all three components are present in the intended ratio.
The copper complex receives specific attention. Complexed and uncomplexed GHK differ in both mass and retention, so a lot in which copper has dissociated is analytically distinguishable — and is a different test article even though the peptide sequence has not changed.
Endotoxin by kinetic chromogenic LAL, residual solvents by gas chromatography and water content by Karl Fischer are determined on the finished blend, because blending and re-lyophilization are process steps in their own right.
Common research questions about GLOW
Is GLOW the same as KLOW? No. GLOW is the three-component formulation; KLOW adds KPV and glutathione. Records should name the blend and the per-component mass so the test article is reproducible.
Why supply a blend rather than three vials? A single lot, a single certificate and a fixed ratio in every aliquot remove ratio variability between runs. For attribution work — deciding which component produced an observation — separate vials remain the correct choice.
What analytical evidence should accompany a GLOW lot? Per-component chromatograms for the actual lot, LC-MS identity for each component, the mass ratio in the vial, plus endotoxin, residual solvent and water content on the finished blend.
Does the copper content matter for handling? Yes. It is the reason light protection and chelator-free diluents are specified, and the reason a certificate that does not distinguish complexed from uncomplexed GHK leaves an open question about the material.
