Contents: BPC-157 10 mg + TB-500 10 mg + GHK-Cu 50 mg + KPV 10 mg (four separate vials) · Purity: ≥99% by reverse-phase HPLC · Identity: ESI-MS confirmed
The KLOW Kit is the broadest of the repair-focused kits, bringing together four peptides that cover repair, copper-peptide biology, and anti-inflammatory signaling. BPC-157 and TB-500 anchor the repair side, GHK-Cu adds the copper-tripeptide angle, and KPV contributes alpha-MSH-related anti-inflammatory research. All four come as separate vials with their own documentation.
Structure & Identity
The kit brings together four 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 full-length thymosin beta-4, a 43-residue 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). KPV is the tripeptide Lys-Pro-Val, the C-terminal fragment of alpha-MSH (CAS 67727-97-3, MW 342.4 Da).
Research Background
The four peptides represent several distinct research threads.
- BPC-157 repair. Studied in tissue-repair and gastrointestinal research [PMID: 30915550].
- TB-500 actin biology. An actin-sequestering repair peptide [PMID: 16099219].
- GHK-Cu copper biology. Studied for oxidative-stress and tissue-repair signaling tied to its copper ion [PMID: 22666519].
- GHK-Cu tissue repair. Linked to healing outcomes in a rat model [PMID: 25731775].
- KPV anti-inflammatory. The alpha-MSH C-terminal fragment studied for anti-inflammatory activity [PMID: 12750433].
These are research contexts, not approved uses, and the kit is intended for laboratory study.

Storage & Handling
Keep all four 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. Note that GHK-Cu reconstitutes to a blue-tinged solution, which is normal for the copper complex.
Storage and Handling Guide
Quality Assurance
All four 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 KLOW Kit?
Four separate vials: BPC-157 10 mg, TB-500 10 mg, GHK-Cu 50 mg, and KPV 10 mg. The kit is studied across repair, copper-peptide, and anti-inflammatory research and is supplied for research use only.
What does “KLOW” refer to?
It is the kit name for this four-peptide combination. The letters reflect the components commonly grouped in this kind of research set.
Are the four 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 have its own COA?
Yes. Each of the four peptides is tested separately and has its own published batch-specific certificate of analysis.
Is the KLOW 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.
