I think there’s all sorts of rules and caveats when you’re dealing with the FAA, dadx. Sometimes I think they don’t even know what they allow, as it can take many months for approval, sometimes when things appear simple. But I just looked it up on an approved medication website, so who knows how old or accurate that info was. Maybe it’s for people just starting something. I don’t know anyone who actually takes the stuff, that I could ask.
