Ariza is a dumb****, so I don't think he's got any training beyond what any fool can garner from reading about the subject in books. It's the chemists that you have to keep an eye out for like, oh whom else... Memo. The problem with PEDs is sourcing it, then distribution, nevermind the qualifications to administer them. Does that seem like something Ariza is capable of when he's not kicking an old fart with Parkinsons?
I have a feeling both Manny and Floyd will both be found guilty. Manny in the past, and Floyd both past and present.
