BPC-157 / TB-500 Blend 10mg — Co-Lyophilised Research Preparation for Repair Biology Studies
BPC-157 / TB-500 Blend 10mg is a research-grade co-lyophilised preparation containing 5mg BPC-157 and 5mg TB-500 per vial. Both components are supplied as a single lyophilised preparation for laboratory research investigating the individual and combined biochemical properties of these two compounds in cell-based and tissue models. Each vial is verified by RP-HPLC to ≥99.0% purity for each component, with identity confirmed by ESI-MS for both peptides. Batch-specific analytical documentation is available through the AbsoluteBioLab CoA Portal.
This blend format is provided as a research convenience preparation. Researchers investigating the individual biochemical properties of BPC-157 or TB-500 should refer to the standalone vial products: BPC-157 10mg and TB-500 10mg. The blend format does not imply synergistic activity, complementary mechanisms, or a recommended research protocol — these are distinct research compounds with separate published evidence bases.

Analytical Specification
| Test Parameter | Method | Specification |
|---|---|---|
| Purity — BPC-157 (RP-HPLC) | C18 column, UV 220 nm | ≥99.0% |
| Purity — TB-500 (RP-HPLC) | C18 column, UV 220 nm | ≥99.0% |
| Identity — Both components (ESI-MS) | Electrospray ionisation MS | Both peptide masses confirmed against theoretical values in single acquisition |
| Endotoxin (LAL) | Kinetic turbidimetric LAL | <1.0 EU/mg |
| Appearance | Visual inspection | White lyophilised powder |
Analytical note: The two-component co-lyophilised format requires independent chromatographic resolution of BPC-157 and TB-500 within the same preparation. Both components are resolved on a C18 column under gradient conditions and quantified by area normalisation. ESI-MS is performed on the combined preparation, with both peptide masses confirmed against theoretical values in a single acquisition.
Research Context
BPC-157 Research Context
BPC-157 (body protection compound) is a synthetic pentadecapeptide derived from a sequence within human gastric juice protein BPC. Research using BPC-157 in animal models has examined its effects on angiogenesis, nitric oxide signalling, and growth factor receptor expression in tissue repair models. The published BPC-157 evidence base is primarily from rodent models; human clinical data is limited. Refer to the standalone BPC-157 10mg product page for the full research context.
TB-500 Research Context
TB-500 (Ac-LKKTETQ) is a synthetic heptapeptide corresponding to residues 17–23 of thymosin beta-4. Research using TB-500 in animal models has examined actin-binding properties, cell migration, and angiogenesis in tissue repair models. TB-500 evidence and thymosin beta-4 (Tβ4) evidence are distinct — TB-500 is not Tβ4 and should not be described as such. Refer to the standalone TB-500 10mg product page for the full research context.
Blend Format Research Considerations
The blend format provides a single preparation containing both compounds for research convenience. Researchers should note that the blend format does not imply synergistic activity, complementary mechanisms, or a recommended research protocol. BPC-157 and TB-500 have separate published evidence bases and distinct mechanisms of action. Researchers investigating the individual biochemical properties of either compound should use the standalone vial products. The blend format is appropriate for research designs that require both compounds to be present in the same preparation, such as comparative or combinatorial cell-based assay systems.
Storage and Transport
| Condition | Specification |
|---|---|
| Long-Term Storage | −20°C, protected from light and moisture |
| Stability Period | Stated on the batch-specific CoA |
| Transit | Ambient; cold-chain packaging included for applicable orders |
Batch Documentation
Every batch of BPC-157 / TB-500 Blend 10mg dispatched by AbsoluteBioLab is accompanied by a batch-specific Certificate of Analysis documenting the purity and identity of both components. CoA documents are available via the Certificate of Analysis Portal. For further information on repair biology research compounds, refer to the Repair Research Peptide Comparison guide.
Frequently Asked Questions
What is the difference between this blend and the standalone BPC-157 and TB-500 products?
The blend vial contains 5mg BPC-157 + 5mg TB-500 co-lyophilised in a single vial. The standalone products contain 10mg of a single compound. The blend format is a research convenience preparation — it does not imply synergistic activity or a recommended research protocol. Researchers investigating the individual biochemical properties of either compound should use the standalone products.
Is TB-500 the same as thymosin beta-4?
No. TB-500 (Ac-LKKTETQ, CAS 77591-33-4) is a synthetic heptapeptide corresponding to residues 17–23 of thymosin beta-4 (Tβ4, CAS 61512-21-8). TB-500 is not Tβ4 and should not be described as such. They are distinct molecular entities with different sequences, molecular weights, and published research contexts.
Where can I access the Certificate of Analysis?
Batch-specific CoA documents are available via the AbsoluteBioLab CoA Portal.
