Read a deep dive on the 'all-purpose healing' peptide BPC-157

The unapproved peptide—which has received glowing testimonials from bodybuilders, biohackers, popular podcasters, and some in the MAHA movement— is often sourced from China. It has been used for myriad conditions. But scientific questions about the substance abound, including whether it's truly a natural substance produced by the human body, since genetic material that codes for its unique amino acid sequence hasn't been found in the human genome or the gut microbiome. Other unknowns include how it works in the body, which receptors it targets, and its safety, since evidence beyond anecdotes remains scant in humans.

Peptides may have predated ribosomes—the cell's protein factory

Some scientists have hypothesized that peptides and RNA molecules may have coevolved as a single, mixed "chimeric" molecule, fueling the beginning of protein production and predating a primitive version of the ribosome. All life today uses ribosomes to make peptides. (Some users may experience a paywall.)
