Mechanism & Target Class

At the molecular level, this blend combines two structurally distinct peptides. BPC-157 is a 15-amino-acid peptide (GEPPPGKPADDAGLV) examined in indexed work using endothelial and fibroblast model systems, where readouts include tube-formation assays and phosphorylation measurements in cultured cells. TB-500 is characterized in peer-reviewed analytical work as an N-terminally acetylated heptapeptide, Ac-LKKTETQ, corresponding to a short actin-binding sequence motif within a larger endogenous peptide; related literature maps this sequence to actin-associated chemistry, cell-adhesion model systems, and migration-linked assays.

Storage & Handling

Lyophilized
Keep sealed, dry, and protected from light; general synthetic-peptide handling guidance recommends storage at −20 °C or colder.
Handling
Reconstituted peptide stability is sequence-dependent; moisture, repeated freeze-thaw cycles, strong alkaline conditions, and light exposure can reduce integrity. Component-specific stability for this exact two-peptide formulation was not specifically characterized in the sources reviewed.
