Contents: BPC-157 10 mg + TB-500 10 mg + GHK-Cu 50 mg (three separate vials) · Purity: ≥99% by reverse-phase HPLC · Identity: ESI-MS confirmed
The GLOW Kit combines three peptides with a shared interest in repair and skin biology: BPC-157 and TB-500 for tissue-repair research, and GHK-Cu, the copper tripeptide long studied in skin and antioxidant contexts. All three come as separate vials, each with its own documentation, so they can be studied individually or together.
Structure & Identity
This kit supplies three separate peptides, each with its own identity. BPC-157 is a 15-amino-acid gastric-derived peptide (CAS 137525-51-0, MW 1419.5 Da). TB-500 is thymosin beta-4 in full, a 43-residue acetylated peptide (Ac-SDKPTSFDKSKLKKTETQEKNPLPSKETIEQEKQAGES, CAS 77591-33-4, MW 4963.55 Da), a fragment of thymosin beta-4, not the unrelated peptide Ac-SDKP, and its LKKTETQ region carries its actin-regulating role. GHK-Cu is the copper tripeptide Gly-His-Lys complexed with copper(II) (CAS 89030-95-5, MW ~404 Da).
Research Background
The three peptides cover repair and skin-biology research threads.
- BPC-157 repair. Studied in tissue-repair and gastrointestinal models [PMID: 30915550].
- TB-500 actin biology. An actin-sequestering protein tied to cell migration [PMID: 16099219].
- GHK-Cu oxidative stress. Studied for protection against oxidative change [PMID: 22666519].
- GHK-Cu tissue repair. Linked to healing in a rat model [PMID: 25731775].
- Skin-biology thread. GHK-Cu’s copper-peptide role connects the kit to skin research.
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 it within about two weeks. Warm a vial to room temperature before opening, and avoid repeated freeze-thaw cycles. GHK-Cu reconstitutes to a blue-tinged solution, which is normal for the copper complex.
Storage and Handling Guide
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 has its own published 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. The kit is studied across repair and skin-biology research and is supplied for research use only.
How is the GLOW Kit different from the GLOW blend?
The kit provides the three peptides as separate vials; the GLOW blend pre-combines them in one vial. The kit lets researchers handle each peptide independently.
Is TB-500 in this kit the “Ac-SDKP” fragment?
No. TB-500 is a fragment of thymosin beta-4. Ac-SDKP is a different peptide entirely and is not what TB-500 refers to.
Why is GHK-Cu’s solution blue?
The blue tint comes from the copper(II) ion carried by the GHK tripeptide, which is normal for a genuine GHK-Cu preparation.
Does each vial have its own COA?
Yes. Each of the three peptides is tested separately and has its own published 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.
