The Racing Medication and Testing Consortium (RMTC) has noted that two substances available only through compounding pharmacies are unclassified medications that will be regarded as high-level violations if used in racing.

The RMTC Tactical Research Committee has reviewed data from laboratory analysis of the two substances of concern in racing that have been marketed as powerfully effective drugs: "Purple Pain" and "TB-500."

Both of these substances are non-FDA-approved and only available through compounding pharmacies. Accordingly, under the Association of Racing Commissioners International (RCI) guideline regarding unclassified medications and foreign substances, the RMTC recommends that any administration of these substances be treated as a prohibited act and that a finding for either substance or their metabolites be treated as a finding for a prohibited substance.

As such, these substances should be treated as an Association of Racing Commissioners Class 1 substance (highest level violation) with Class A penalty guidelines (most severe) attached
