One thing that is still open after Dr.SurgeonPGH’s answer:

Was that from a primary source or from a summary of one?

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.

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)

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Printing the relevant bit and taking it with me.

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.
