## FAQ

### Why is BPC-157 more stable than other research peptides?

Its sequence contains several proline residues that stiffen the peptide chain and block protease cleavage sites. This architecture is inherited from a stomach-fluid protein that must withstand acid and pepsin, making it unusually resistant to enzymatic and thermal degradation.

### What enzymes break down peptides and why can't they easily cleave BPC-157?

Proteases such as pepsin and trypsin recognize flexible backbone regions between amino acids. Proline-proline pairs in BPC-157 introduce rigid kinks that sterically block protease active sites, slowing or preventing cleavage under conditions that rapidly degrade standard peptides.

### How long does BPC-157 remain detectable in biological tissue samples during in vitro or animal research?

Peer-reviewed animal studies have detected intact BPC-157 in tissue samples hours after administration, a notably longer window than comparable peptides. Exact duration varies by matrix and study design; researchers should consult primary literature for specific figures.
