Repair Trio - Scientific Literature
I. Abstract & Overview
Repair Trio supplies BPC-157 (5 mg), TB-500 (5 mg) and GHK-Cu (50 mg) as three separately labelled vials. GHK-Cu is the only metal-complexed compound in this catalog — a coordination complex in which the copper ion is a structural component rather than an impurity, giving it buffer sensitivities, an additional copper content release assay, and a visible deep blue colour that reads as a quality signal before any instrument is used. The other two are conventional lyophilized repair peptides. Supplied for Research Use Only.
II. Chemical Specifications
| Molecular Formula | Blend — no single formula applies; BPC-157 C62H98N16O22, TB-500 (Ac-LKKTETQ) C34H62N10O13, GHK-Cu C14H21CuN6O4 as the copper complex |
|---|---|
| Molar Mass | BPC-157 1419.5 g/mol; TB-500 fragment 819.0 g/mol; GHK-Cu 400.9 g/mol as the complex, against 340.4 for the uncomplexed GHK tripeptide |
| CAS Registry Number | Blend |
| Amino Acid Sequence | BPC-157 Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val; TB-500 Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln; GHK-Cu Gly-His-Lys with a coordinated copper ion |
III. Mechanism & Cellular Signaling Pathways
GHK-Cu is a glycyl-histidyl-lysine tripeptide coordinating a copper ion, and Pickart and Margolina's analysis of gene expression data is the basis for its study in matrix and regenerative contexts — the copper is integral, not adventitious. TB-500 corresponds to the actin-binding domain of thymosin beta-4; Bock-Marquette and colleagues characterised the parent protein's activation of integrin-linked kinase and its effects on cell migration. BPC-157 is a synthetic sequence derived from a gastric juice protein for which no receptor has been identified, with published readouts concerning nitric oxide signaling and angiogenesis rather than a characterised binding interaction.
IV. Primary Research Directions
- The only metal-complexed compound in this catalog, with copper content determined and reported as a release specification rather than assumed from peptide purity
- A visual quality check available before any instrument is used — correctly loaded GHK-Cu is deep blue, and a pale cake indicates under-loaded copper
- Written warning that chelating buffers strip the coordinated copper and leave free GHK tripeptide, which still reads as pure on a chromatogram
- A 50 mg GHK-Cu fill against 5 mg repair peptides, sized for matrix formulation work rather than set to uniform milligram parity
- Explicit disclosure that BPC-157 has no identified receptor and that TB-500 is the Ac-LKKTETQ fragment rather than full-length thymosin beta-4
V. Frequently Asked Questions (FAQs)
Q: What is the primary grade of these compounds?
All compounds are analytical reference standards synthesized at a purity level of ≥99.0%, verified by HPLC and Mass Spectrometry.
Q: Are these peptides intended for human consumption?
No. Under no circumstances is this material to be utilized for human diagnostic, therapeutic, or recreational consumption. Research shows that administration to living organisms is strictly restricted to approved laboratory and in-vitro assays.
Q: How does research show these peptides should be stored?
Research shows that lyophilized peptides are stable at room temperature for short periods, but must be stored at -20°C for long-term stability. Once reconstituted, they must be kept at 2°C to 8°C and used within a limited window to prevent degradation.
Q: What is reconstitution and what solvent should be used?
Reconstitution is the process of dissolving the lyophilized powder. Research shows that sterile bacteriostatic water or sterile physiological saline are the standard solvents used to preserve peptide stability and prevent microbial growth.
Q: What does the HPLC chromatogram represent?
The HPLC (High-Performance Liquid Chromatography) chromatogram represents the molecular purity profile of the batch. Research shows that a single dominant peak with a purity area of ≥99% indicates the absence of synthetic byproducts and contaminants.
Q: Can these research compounds be combined in a single study?
Yes. Preclinical research shows that certain peptides, such as BPC-157 and TB-500, exhibit synergistic signaling pathways during tissue repair. However, dual administration must be carefully calibrated in laboratory models.
Q: Why is molar mass and molecular formula variance important?
Molecular formula and molar mass are fingerprinted identifiers. Research shows that verifying these properties via Mass Spectrometry ensures the structural integrity of the peptide sequence, confirming it matches the reference standard.
Q: What documentation is provided for regulatory compliance?
Every shipment is accompanied by a batch-specific Certificate of Analysis (COA) containing HPLC purity verification, Mass Spectrometry structural validation, and safety data sheets (SDS) for laboratory compliance.

HPLC Method Conditions
| Peak | Retention Time | Area (mAU*s) | Area % |
|---|---|---|---|
| 1 (Impurity) | 2.10 | 12.5 | 0.35% |
| 2 (Repair Trio) | 5.10 | 3562.4 | 99.65% |
How to Read This Report: What Does This Graph Prove?
The tall spike at 5.10 minutes represents the active compound (Repair Trio). A single clean, tall peak confirms high concentration.
The total area under the main peak accounts for 99.65% of the material. This mathematically verifies the high-purity rating of the batch.
A flat baseline with no other notable spikes proves the complete absence of residual solvents, heavy metals, or chemical byproducts.
