It'd be funnier exccept that the answer is "maybe he does." He's got enough money to have the entire hospital follow him around if he wanted so a crooked doc juicing him up is probably exactly what was happening. Remember the reports about all the stuff being dispensed during Rumps first term?

Michael Jackson had a personal doctor anesthetize him nightly so he could sleep, now that we're talking about it I'd be willing to bet that these guys are doing. Just paying some shady doctor to travel around with them dispensing whatever they want. It's not illegal if you have a doctor say you need it!
