Eddie Alvarez got wind of Gilbert Melendez's recent drug test failure for exogenous testosterone, but it doesn't sound like the former Bellator champ is taking a very hard line stance on the issue.
While you'd have to go a long way to find a fighter that is publicly vocal against the new PED regulations, I think it'd take a lot less looking to find fighters who just don't see it as a major issue, or one that they are particularly invested in. One fighter who seems to fall under that umbrella (and perhaps more so coming off a win) is Eddie Alvarez.
