What actually differs
The clearest difference is class: BPC-157 is a pentadecapeptide, TB-500 is a thymosin beta-4 fragment. They are not supplied the same way. BPC-157 comes as a lyophilised powder in a vial, or as a pre-filled pen solution, TB-500 as a lyophilised powder in a vial, or pre-filled pen solution. Half-life differs as well: Short in circulation; minutes to a few hours in published models for BPC-157 against Longer tissue residence than BPC-157 in published models for TB-500.
