How I verify my compounded peptide — March 2026

Adding the clinical framing, because it changes how the question reads.

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

This is my experience too, for whatever a second data point is worth.

503A vs 503B compounding pharmacies for compounded supply — this distinction matters enormously:

I strongly recommend 503B facilities. The FDA oversight and cGMP requirements mean more consistent product quality.

Compounded has been just as effective for me. If compounded supply is the concern, the COA from my 503B pharmacy shows 99.1% purity. Verified by Janoshik.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
