How much is known

No human trials

Very limited. One retrospective knee-injection chart review: of 16 patients reached, 12 got BPC-157 alone (11 improved) and 4 got BPC-157 plus thymosin beta-4 (3 of 4 improved), with no control group. A 2025 review recounts it as 7 of 12 with relief over 6 months. The rest is animal work on each peptide separately.
