Clevenger is not known to have tested positive for either of the banned drugs he is alleged to have used: a hard-to-detect and widely available peptide called BP-157 that some believe is key to injury recovery
It was first synthesized and tested in the late 1980s in Russia, where it can be used for research purposes
