NutraBio, one of the manufacturers of a supplement that boxer Ryan Garcia’s legal team says contained traces of a banned substance, is firing back at the allegation.

Garcia’s legal team revealed test results for two different supplements that Garcia declared on VADA (Voluntary Anti-Doping Association) Doping Control forms prior to his fight with Devin Haney, against whom his win came under controversy after A and B samples from Garcia’s initial tests came back positive for ostarine, which is a banned performance-enhancing substance.

Garcia stunned many when he took down Haney, though the WBC super lightweight championship belt wasn’t up for grabs after the former failed his weigh-in.
