BPC-157 / TB-500 Blend

This blend combines two structurally and mechanistically distinct peptides: BPC-157 (a 15-amino-acid pentadecapeptide, MW ~1419 Da, sequence GEPPPGKPADDAGLV) and TB-500 (a synthetic 43-amino-acid replica of Thymosin Beta-4, MW ~4921 Da). The peptides are co-lyophilized and maintain stability in the blended format. The rationale studied in research is that their mechanisms are complementary: BPC-157 acts largely at the local tissue level, while TB-500, as a G-actin sequestering peptide, is associated with cytoskeletal reorganization and cell migration more systemically.

The co-lyophilized blend is stored lyophilized at -20C and reconstituted with bacteriostatic water directed gently against the vial wall. The reconstituted solution is stored at 2-8C and not frozen. Both peptides are stable across the same pH range (4.0-8.0).
