From the other side of the consultation, briefly.

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

Price comparison for compounded supply across sources I've used:

SourceMonthly CostTypePurity Verified
Brand (Ozempic)$918FDA-approvedN/A (pharma)
503B Compounding$148cGMP compoundedYes (in-house)
503A Compounding$108Patient-specificVaries
Research peptide$58Not for human useOften Janoshik

I use the 503B option — best balance of quality, cost, and legality. The brand price is insane but insurance can help if you qualify.

Can confirm. Same sequence, different timescale.

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.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. Carry on.
