Description
Structure & Identity
The kit contains three separate peptides, each keeping its own structure. BPC-157 is the 15-mer body-protection-compound peptide (CAS 137525-51-0, MW 1419.5 Da). TB-500 is thymosin beta-4, an acetylated peptide (CAS 77591-33-4, MW 4963.55 Da), studied for the actin-binding activity of its LKKTETQ region. GHK-Cu is the copper tripeptide glycyl-histidyl-lysine bound to copper(II) (CAS 89030-95-5, MW ~404 Da).
Research Background
The three peptides represent several distinct research threads.
- BPC-157 repair. A synthetic pentadecapeptide studied in preclinical models of angiogenesis and cytoprotection [PMID: 30915550].
- TB-500 actin biology. An actin-sequestering peptide, a fragment of thymosin beta-4, studied in cell-migration research [PMID: 16099219].
- GHK-Cu copper biology. Studied for redox and copper-dependent enzyme signalling tied to its copper ion [PMID: 22666519].
- GHK-Cu connective tissue. Linked to collagen and extracellular-matrix (ECM) readouts in a rat model [PMID: 25731775].
These are research contexts, not approved uses, and the kit is intended for laboratory study.

Storage & Handling
Keep all three sealed vials frozen at -20°C and shielded from light until use. After reconstitution, store each solution at 2-8°C and use in your study it within about two weeks. Warm a vial to room temperature before opening, and avoid repeated freeze-thaw cycles. Note that GHK-Cu reconstitutes to a blue-tinged solution, which is normal for the copper complex.
Quality Assurance
All three peptides are produced under research-grade manufacturing controls and verified by an independent lab before release. Purity is measured by reverse-phase HPLC and identity by mass spectrometry, with testing carried out by third-party laboratories, including Janoshik Analytical and domestic US labs. Each vial ships with its own batch-specific certificate of analysis.
Frequently Asked Questions
What is in the GLOW kit?
Three separate vials: BPC-157 10 mg, TB-500 10 mg, and GHK-Cu 50 mg.
What does “GLOW” refer to?
It is the kit name for this three-peptide combination. The letters reflect the components commonly grouped in this kind of research set.
Are the three peptides combined in one vial?
No. Each comes in its own separate vial, so researchers can reconstitute and study each independently.
Why is GHK-Cu’s solution blue?
The blue tint comes from the copper(II) ion held by the GHK tripeptide. A genuine GHK-Cu solution carries that characteristic color.
Does each vial come with its own COA?
Yes. Each of the three peptides is tested separately and ships with its own batch-specific certificate of analysis.
Is the GLOW kit FDA approved?
No. None of the components is FDA approved. The kit is a research-use-only preparation, not for human or veterinary use.
How should the kit be stored?
Keep all powders frozen at -20°C and protected from light. Once reconstituted for research, store each solution at 2-8°C and use within about two weeks.
How are the peptides verified?
Each is tested to ≥99% purity by reverse-phase HPLC with mass-spec identity confirmation by an independent lab.
