Recovery, By the Literature
A plain-language tour of the tissue-repair peptides researchers study most, and where the evidence currently stands.
The 'recovery' corner of peptide research is one of the most discussed and least settled. Here's what the most-studied compounds actually are, and an honest read on the state of the evidence.
BPC-157
BPC-157 is a synthetic pentadecapeptide — a 15-amino-acid sequence — derived from a protein found in gastric juice. It's studied in models of tissue protection and is one of the most frequently referenced compounds in the recovery literature. Most of that literature is preclinical.
TB-500 and thymosin β4
TB-500 is a synthetic fragment related to thymosin β4, a naturally occurring protein involved in cell migration and actin regulation. In research it's frequently paired with BPC-157 because the two are studied for complementary mechanisms — one often framed around local tissue processes, the other around systemic cell motility.
The supporting cast
KPV (a fragment related to α-MSH) and LL-37 (a cathelicidin-derived peptide) appear in adjacent research on inflammatory signaling. They're studied for different mechanisms and shouldn't be lumped together with the repair peptides above.
Reading the evidence honestly
The crucial caveat: much of the recovery literature is animal or in-vitro work, and well-controlled human data is limited. Mechanistic plausibility is not the same as a demonstrated outcome. Treat these as research subjects, not conclusions.
