The shortage clause is the answer to the second question and it is a subtraction rather than an addition.

That reframing is the part I needed. Printing the relevant bit and taking it with me.

From the other side of the consultation, briefly.

Compounding pharmacy licensing verification for compounded supply: before ordering, verify your pharmacy's credentials:

  1. State Board of Pharmacy license — check on your state BOP website
  2. FDA registration (for 503B) — check on fda.gov
  3. DEA registration if handling controlled substances
  4. PCAB accreditation — voluntary but demonstrates commitment to quality
  5. USP <797>/<800> compliance for sterile compounding

This takes 10 minutes of research and could save you from receiving substandard or unsafe medication.

Compounding pharmacy customer here with experience relevant to compounded supply.

Vendor communication red flags for compounded supply:

  • Won't provide COA before purchase — walk away
  • Claims "100% pure" without analytical data — unrealistic
  • No physical address or phone number — accountability matters
  • Pushes you to buy more than you need — pressure tactics
  • Won't answer questions about their compounding process — transparency is key
  • Payment only via crypto or wire transfer — legitimate pharmacies accept cards

A legitimate compounding pharmacy operates like a healthcare business, not a gray market dealer.

They are two different exemptions from the same federal requirements and they buy different things.

503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:

Feature503A503B
RegulationState Board of PharmacyFDA-registered
PrescriptionRequired (patient-specific)Can compound without patient Rx
TestingVaries by statecGMP required
ScaleSmall batchesLarger production
Quality consistencyVariableGenerally higher

I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.
