What is in it
BPC-157
Body Protection Compound-157 · PL 14736
BPC-157 is a lab-made chain of 15 amino acids based on part of a protein found in human stomach juice.
TB-500 / Thymosin beta-4
Thymosin beta-4 · Tβ4
Thymosin beta-4 (Tβ4) is a natural 43-amino-acid protein found in almost every cell, where it helps control the cell's internal skeleton and cell movement.
Is there evidence for the combination?
One rat study has tested them together. In 32 rats with repaired Achilles tendons, TB-500 alone improved tendon strength, and the combination did no better than TB-500 alone 1. No human study has tested the combination.
