How long does TB-500 stay in your system?

Nobody knows. The FDA's 2026 review found no published study of how the body handles TB-500 in people. So there is no measured clearance time or half-life in people to quote. Any time claimed online is borrowed from the unrelated full-length parent peptide, thymosin beta-4. It was not measured for the piece sold as TB-500.

Part of healing and recovery peptides. BPC-157, TB-500, GHK-Cu, and the tissue repair family, including what actually has human data.
