Will peptides fail a drug test?

It depends entirely on the test and the compound. Standard workplace drug screens generally do not test for research peptides at all, but sport specific anti-doping tests do target several of them directly: this site's own legal status data lists BPC-157, TB-500, ipamorelin, CJC-1295, and GHRP-2 as prohibited in sport under the World Anti-Doping Agency code, each listed separately by compound rather than as a blanket category rule.
