Why do people cycle BPC-157?

Usually because a forum or a vendor printed four to eight weeks as if it were a finding. Published human trials do not establish an on/off schedule for BPC-157. Its plasma half-life was under 30 minutes in a two-person pilot, which is a clearance fact, not a reason to take a break. No published study has looked for tolerance or a rebound from stopping. Community protocols are unverified. This site does not invent a schedule. Full detail at /cycling.

Part of cycling and clearance. Whether peptides need a break, what a half-life actually tells you, and where a real cycling mechanism has been measured. Full detail at /cycling.
