Can confirm. Same sequence, different timescale. Posting only so the count is not one.

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 4 hours. They answered my questions about reconstitution thoroughly and professionally.

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

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.

A narrower follow-up, since the general answer is now clear:

How would you tell the difference between that and the alternative explanation?

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. Thread quality here is what the rules are for. Keep it up.
