Your body is constantly maintaining and repairing itself.

When tissue is damaged, the body starts a complicated repair process. Cells communicate with one another, blood flow to the area can change, and new tissue begins forming.

Researchers are interested in BPC-157 because laboratory studies suggest it may interact with some of the biological processes involved in this repair response.

For example, researchers have studied it in models involving tendons and ligaments — the strong connective tissues that help attach muscles and bones and stabilize joints.

It has also been studied in digestive-system research because the lining of the stomach and intestines is another type of tissue that constantly needs to protect and repair itself.

In simple terms, scientists are using BPC-157 to investigate how damaged or stressed tissue responds and repairs itself.
