This area covers peptides studied in tissue-repair, wound-healing, and recovery research — such as BPC-157 and TB-500. Most of the published work is preclinical (cell and animal studies). None are FDA-approved, and they are sold for laboratory research use only.
BPC-157, TB-500 (a synthetic version of a fragment of thymosin beta-4) and KPV (a small fragment of a melanocortin hormone) are studied in the laboratory for tissue repair, inflammation and wound-healing processes. The great majority of that research is preclinical — done in rodents, in cell cultures, or in test tubes. That kind of work can show biological activity and generate hypotheses, but it does not tell you what happens in people.
For BPC-157 in particular there is a large body of animal literature, much of it from a relatively concentrated set of research groups, describing effects on tendon, muscle, gut and other tissues in rats. What is missing is the next step: well-designed, published, randomized human clinical trials showing that these effects hold up in people, at what exposure, and with what safety profile.
None of these three is approved as a drug by the FDA, and they are not permitted as dietary-supplement ingredients in the US. Their efficacy, correct handling, and long-term safety in humans are simply unproven. Honest bottom line: this is an area of active laboratory interest, not established human medicine.

ARA-290 (cibinetide) is a synthetic 11-amino-acid peptide derived from the B-helix of erythropoietin (EPO).
BPC-157 is a synthetic peptide made of 15 amino acids.
KPV is a naturally occurring tripeptide (lysine-proline-valine) corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone.
TB-500 is the market name for a peptide derived from thymosin beta-4, a naturally occurring protein involved in cell and tissue processes.
Thymosin Alpha-1 (thymalfasin) is a synthetic 28-amino-acid, N-acetylated peptide identical to the N-terminal fragment of the naturally occurring thymic protein prothymosin alpha.
