Not trying to be rude, but do you work in tech? I can't imagine presenting this as a plan of record in a design review. And the world runs on good faith. If you call a pharmacy, claim to be some doctor, leave a voice mail, and give their (public) NPI number, there is no validation.
Why aren't people calling in prescriptions for themselves? I guess it just kinda runs on trust me bro and the threat of being put in prison.
