The simplest test: is your name on the vial?
Federal law requires 503A compounding pharmacies to label every patient-specific prescription with the patient’s name, the prescription number, and the pharmacy’s identification — the same legal standard as any prescription you’d pick up at a regular pharmacy.
If a peptide you received — from any source, at any point in the past — did not carry your name, a prescription number, and a licensed pharmacy’s name, it was not compounded under the laws that require sterility testing, patient-specific verification, and pharmacy oversight.
That isn’t a labeling technicality. It’s the reason the labeling exists. Without it, there’s no way to know what you injected, where it came from, or who is accountable.
