How does BPC-157 work?
This site's BPC-157 profile says there is no receptor or molecular target identified in people. The FDA's 2026 review gave that missing target as one reason it could not judge whether the claimed effects make biological sense. The work in people on this site that bears on how it works is small. After an enema dose, the peptide could not be found in the blood. A two-person early study fit with a half-life in the blood of under 30 minutes. The FDA counted five studies in people with fewer than 110 people in total, none using the shots under the skin or pills most buyers use. Animal research describes new blood vessel growth, nitric oxide signals, and more growth hormone receptors in tendon cells. Those animal findings do not transfer into a counted human healing mechanism. This FAQ does not invent a target. Full record at /compounds/bpc-157.
