Compounding pharmacy licensing verification for compounded supply: before ordering, verify your pharmacy's credentials: State Board of Pharmacy…

Beyond-use dating (BUD) for compounded supply compounded products:

Lyophilized (unreconstituted): typically 9 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 7 days (no preservative!)

Always use BAC water for multi-dose vials. Sterile water has no preservative and supports bacterial growth after first puncture. This is a common and potentially dangerous mistake.

Compounding pharmacy response time test for compounded supply: I email customer service at odd hours to test responsiveness. A pharmacy that can't answer questions promptly is a red flag.

My current pharmacy: average response time 1 hour. They answered my questions about batch-specific COAs thoroughly and professionally.

Communication quality is a proxy for operational quality. A pharmacy that communicates well is likely manufacturing well too.

Following on from VanRx_Mike — and this may be the naive question:

Did your prescriber agree with that reading, and if not what was their objection?

Compounding pharmacy red flag checklist for compounded supply — if ANY of these apply, find a different source:

  1. No verifiable physical address
  2. No pharmacist available for consultation
  3. COA not available or clearly template/fake
  4. Prices dramatically below market ($30-40/month = suspicious)
  5. No prescription required
  6. Ships without cold pack or temperature control
  7. No batch/lot numbers on product labeling
  8. Pushes "research use only" products for human injection

Your health depends on product quality. Don't cut corners on source verification.

Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.
