Healing & Recovery

BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. It consists of 15 amino acids and is notable for its stability in gastric acid, a property uncommon among peptides of its size. Research interest centers on its cytoprotective effects across multiple organ systems, including the gastrointestinal tract, musculoskeletal tissues, and the central nervous system. Unlike many bioactive peptides, BPC-157 has no known natural counterpart at its specific sequence length. It was originally isolated as a fragment of a larger gastric protein and has been studied primarily by research groups at the University of Zagreb. It remains an investigational compound with no regulatory approval for clinical use.

TB-500 is a synthetic version of thymosin beta-4 (Tβ4), a 43-amino acid peptide naturally present in virtually all human and animal cells. Thymosin beta-4 is the primary intracellular G-actin sequestering peptide, playing a central role in cytoskeletal dynamics, cell motility, and tissue repair. The designation "TB-500" refers specifically to the synthetic research-grade form used in investigational settings. The active fragment Ac-SDKP (N-acetyl-seryl-aspartyl-lysyl-proline) is a four-amino acid peptide released by enzymatic cleavage of thymosin beta-4. This tetrapeptide mediates several of the anti-inflammatory and anti-fibrotic effects attributed to the parent molecule. TB-500 remains an unregulated research compound with no clinical approval, though Tβ4-based formulations have entered clinical trials for dermal and ophthalmic applications.
