Retatrutide 20 mg
BPC-157 / TB-500 20 mg (10 mg + 10 mg)
TB-500 10 mg
BPC-157 10 mg, Pack of 5
Third-party tested: HPLC-UV purity and LC-MS identity are reported on the Certificate of Analysis for the lot listed in the Specifications tab (see our COA page).
Five vials of BPC-157 / TB-500, each a lyophilized powder labeled 20 mg. Each vial is a pre-mixed research material containing two peptides, BPC-157 and TB-500 (identified on the batch COA as BPC-157 and thymosin beta-4 by LC-MS), supplied for in vitro and analytical research.
About the peptides
BPC-157 is a synthetic 15-amino-acid peptide studied in cell-based models of angiogenesis and cell-signaling pathways.
TB-500 is identified on the batch COA as thymosin beta-4, an actin-binding peptide studied in cell-migration and differentiation research.
Each peptide is studied separately in the published literature. Peptix makes no claims about the effects of this material.
