Materials and methods Animals Adult (810weekold), male C57BL/6 mice (Jackson Laboratories, Bar Harbor, ME) weighing between 20 and 25 g were used

BPC-157/TB-500 is a synthetic peptide blend composed of two defined amino acid sequences produced through controlled peptide synthesis

Physicochemical characterization included particle size distribution, polydispersity index (PDI), and zeta potential (ZP) analysis by dynamic light scattering (DLS), with measurements performed in triplicate (Table 1)

Compounded peptides ship with specific reconstitution instructions printed on the box or vial

Convenient No needles required, no water needed, and easy to take anywhere
