BPC-157 + TB-500 20 mg

BPC-157 + TB-500 for research: identity and specifications

BPC-157 + TB-500 is a blend of two synthetic peptides in a single vial: BPC-157, a pentadecapeptide (CAS 137525-51-0), and TB-500, an acetylated heptapeptide (CAS 885340-08-9). Supplied as a 20 mg total vial (10 mg + 10 mg), lyophilized powder, with no fillers, carriers or excipients, at ≥98% purity by HPLC, made by SPPS and purified under analytical controls documented for every lot.

Scientific background

BPC-157 is a 15-amino-acid sequence derived from a gastric juice protein, investigated in experimental models of peptide signaling, cell migration and growth factor expression. TB-500, an acetylated fragment associated with the actin-binding region of thymosin β4, is studied for its role in actin cytoskeleton dynamics, cell motility and in vitro angiogenesis assays.

Preclinical literature examines both compounds, alone or together, in rodent models of musculoskeletal tissue response and in cell culture, always under controlled bench conditions and without extrapolating results to human or veterinary use.

• Peptide signaling and cell migration in culture
• Actin cytoskeleton dynamics in vitro
• Angiogenesis assays in cell models
• Musculoskeletal tissue response in rodent models

Technical specifications

Analytical quality and chain of custody

Every lot of BPC-157 + TB-500 is synthesized in registered facilities, with independent analytical verification by third-party laboratories and full chain-of-custody documentation. The certificate of analysis (COA) for each lot can be reviewed before purchase, recording HPLC purity and the other quality-control parameters used to release the material.

Reconstitution and laboratory handling

As a bench procedure, the lyophilized vial is reconstituted with a known volume of a suitable solvent, added along the inner wall of the vial, followed by gentle swirling until fully dissolved, without vigorous shaking. The reconstituted solution should be kept refrigerated and protected from light, and used in controlled assays within the stability period validated by the laboratory. Handling must be performed only by qualified personnel, in a bench environment suitable for in vitro experimentation, with lot number and storage conditions documented according to good laboratory practice.
