I guess you're suggesting that they rejected my prescription because of supply issues, they openly said it was because it was suspicious (3-mo in cash), and also Vyvanse hasn't had shortages like generic amphetamine in 2022-2023.

Also, I think you mean OTC amphetamine alternatives since amphetamine is sched I.

These pharmacists have very real personal liability if they end up getting fingered as being a supplier of components used to make illegal drugs. That's why they look askance at this prescription.

Not supply issues, meth manufacturing suspicion. Yeah, precursors to their manufacture.

Amphetamine (Dexedrine) is schedule II, not schedule I. Doctors cannot generally prescribe schedule I substances like LSD. Pseudoephedrine is a substituted amphetamine so referring to it as "an OTC amphetamine" is technically reasonable although potentially misleading.
