Start with the word that stopped you. Each definition points back to a practical check.
Core terms
- Peptide
- Peptides are made from small strings of amino acids, the parts that form proteins; calling something a peptide does not show that it is safe or legal.
- FDA-approved
- As of September 2026, FDA approval means the FDA reviewed a specific product for a named use; this is different from a facility being registered with the FDA.
- Compounded medicine
- As of September 2026, this is a medicine mixed or made to order by a pharmacy or clinician; it is not FDA-approved.
- 503A pharmacy
- As of September 2026, this is a regular pharmacy that makes medicine for one named patient with a prescription.
- 503B outsourcing facility
- As of September 2026, this is a larger facility that makes batches of sterile medicines—medicines made to be free of germs—and follows federal factory-quality rules.
- NDC number
- A code in a government drug directory; having one does not mean the FDA approved the product.
- Telehealth
- Care given by video, phone, or an online exchange while the patient and clinician are in different places.
- Static questionnaire
- A fixed form that cannot ask a follow-up question; the Federation of State Medical Boards, a national group of state boards, says that form alone cannot provide a proper medical review.
- Formulary
- A health plan’s list of medicines it covers; the plan may still require approval before it pays.
- Prior authorization
- A step where an insurer must agree to pay before a pharmacy fills the prescription.
- Adverse event
- Anything unwanted that happens while someone is using a medicine; a report does not prove the medicine caused it.
