Bundle (BPC-157 5mg x5 + TB500 5mg x5)

This bundle pairs five individually-supplied vials of BPC-157 (5mg) with five individually-supplied vials of Thymosin Beta 4/TB-500 (5mg), for researchers who want both peptides on hand without committing to a fixed mixing ratio.

Independent Verification Versus a Pre-Mixed Formulation

Because each vial in this bundle contains a single peptide rather than a blended formulation, each is independently verified by HPLC and mass spectrometry against its own single-compound specification, without the added analytical step of confirming a fixed ratio between two co-formulated peptides.

This differs from a pre-mixed blend, where the two peptides would instead be combined into a single formulation at a fixed, manufacturer-set ratio.

Thymosin Beta 4 (TB-500) Actin-Binding Research

Thymosin Beta 4 functions as the principal G-actin sequestering peptide in the cytoplasm, forming a 1:1 complex with monomeric actin that inhibits its polymerization into filaments, a mechanism studied in laboratory research on cell migration and differentiation.¹

BPC-157 Structural Considerations

BPC-157 is a synthetic pentadecapeptide originally derived from a protein found in human gastric juice, distinguished by an unusually high proline content across roughly a quarter of its fifteen residues.

This proline-dense backbone is understood to impose conformational rigidity, a structural feature researchers have linked to the peptide's reported resistance to enzymatic degradation in laboratory assay systems.

Combined Research Applications

Because BPC-157 and Thymosin Beta 4 are studied for distinct cell signaling mechanisms, cytoskeletal actin dynamics for the latter, receptor-independent signaling for the former, researchers may study them side by side to examine multiple pathways within the same experimental model.

Data specific to combined use of these two peptides remains limited, and any such research should be treated as exploratory.

Analytical Verification for Bulk Vial Quantities

With five vials of each peptide supplied together, researchers are encouraged to confirm that certificates of analysis are available for each individual vial or production lot, since synthesis batches can vary even under the same nominal specification.

Storage and Handling in the Laboratory Setting

Both peptides are best kept lyophilized under sub-zero freezer conditions until shortly before use, since peptide bonds become more susceptible to hydrolysis and oxidative breakdown once removed from this stable, freeze-dried state.

With ten vials to manage across this bundle, keeping them organized by peptide and batch simplifies tracking which vials have been opened versus those still sealed in storage.

Important Notice

BPC-157 and Thymosin Beta 4 (TB500) are strictly for in vitro laboratory research purposes only and are not intended for human consumption. These findings do not establish safety, efficacy, or suitability for any human application, and these products have not been evaluated by the FDA or any regulatory agency.

Product Information

This bundle includes 5 vials of BPC-157 at 5mg per vial and 5 vials of Thymosin Beta 4 (TB500) at 5mg per vial, supplied as lyophilized powders for laboratory research use only.
