Following the evidence
A source link helps you check what a claim means.
The misconception
“If a drug appears on a government list, it must be approved.”
The answer
A National Drug Code, shortened to NDC, identifies a drug on a government list. As of September 26, 2026, having this number does not mean the Food and Drug Administration (FDA) approved the medicine.
An entry on a drug list, an approved medicine’s label and a report of a problem answer different questions.
Trace this answerRead the record for the question it answers
A product label
An FDA-approved label describes the specific medicine and uses the agency reviewed. Other products called peptides do not share that approval.
Ask which exact product the label describes, and whether it describes the medicine being offered to you.
A drug-code entry
Ask: “Does this number only identify the drug, or can you show me that FDA approved it for this use?” Ask the doctor to show you the medicine’s entry in Drugs@FDA, its approval records, and explain the approved label.
A report of a problem
FDA cautions that a reported unwanted event does not prove a medicine caused it, or show how often it happens.
Ask what other evidence helps put the report in context.
A statement about research peptides
For BPC-157, FDA says human safety information for the proposed ways of giving it is too limited to tell whether it causes harm.
As of September 26, 2026, missing information does not show that BPC-157 is harmless.
