Clinical perspective, offered as context rather than as advice.

FDA inspection results for compounding pharmacies selling compounded supply: you can look up any 503B facility's FDA inspection history on the FDA website.

Check for: Form 483 observations (violations), warning letters, and recall history. A clean inspection record is a strong indicator of quality. My pharmacy has had 0 Form 483 observations in their last 3 inspections.

This is public information. Use it. Link: fda.gov/inspections-compliance-enforcement-and-criminal-investigations

Mine went the same way, slower. Posting only so the count is not one.

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

Lyophilized (unreconstituted): typically 6 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 24 hours (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.

For compounded supply users considering compounded for the first time: here's a step-by-step guide:

  1. Get a prescription from your doctor (telehealth counts)
  2. Research 503B compounding pharmacies with good community reviews
  3. Verify their FDA registration and inspection history
  4. Request a COA for your specific compound before ordering
  5. Start with a 1-month supply to test
  6. Consider sending a sample to Janoshik for independent verification
  7. Track your response compared to brand (if you were on it previously)
