For compounded supply users considering compounded for the first time: here's a step-by-step guide:
- Get a prescription from your doctor (telehealth counts)
- Research 503B compounding pharmacies with good community reviews
- Verify their FDA registration and inspection history
- Request a COA for your specific compound before ordering
- Start with a 1-month supply to test
- Consider sending a sample to Janoshik for independent verification
- Track your response compared to brand (if you were on it previously)

Beyond-use dating (BUD) for compounded supply compounded products:
Lyophilized (unreconstituted): typically 12 months from compounding date
Reconstituted with BAC water: typically 28-30 days refrigerated
Reconstituted with sterile water: typically 48 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.
