Find the proof behind the claim.

Match the claim to the actual product.

The drug regulator in the US is the Food and Drug Administration (FDA).

Evidence is information offered to support a claim. Ask for the full study; if approval is claimed, also ask for the FDA approval letter and official medicine label.

• Does it name the same ingredient and say whether it is a tablet, injection, or another form?
• Did it involve people with the health concern being discussed?
• What change did it measure?
• What were the limits or unanswered questions?
• How does the person treating you think it applies to your case?

Bring back any words you do not understand. Ask for the main result in a short sentence.

Read the scope of approval.

Semaglutide products with FDA approval as of September 2026 include Ozempic, which controls blood sugar for adults who have type 2 diabetes, and Wegovy for weight management. [a]

With compounding, a pharmacist or doctor prepares medicine for one patient’s needs instead of providing a drug company’s finished product. [b]

Approval for those products does not extend to a pharmacy-made medicine using the same ingredient. [b]

Ask which study supports the proposed medicine for your health problem. For a pharmacy-made medicine, also ask why an approved drug cannot meet your need and how the pharmacist checked the ingredient rules.

Registration is a different record.

FDA registration means a place making or handling drugs has given its details to the agency. As of September 2026, registration does not establish FDA approval of either the place or its medicines. [a]

An NDC is a National Drug Code, an identifying code in a drug directory. [c]

As of September 2026, a product’s NDC is not evidence of FDA approval. [c]

Ask for the FDA approval letter and official medicine label, then check the product name and health uses against the offer.

Treat limited information as an open question.

An immune reaction is the body’s defence system treating an injected substance as an invader. [d]

As of September 2026, FDA’s concerns about several injected peptide ingredients include these reactions, unwanted material in the product, and limited human safety information. [d]

Ask what is known for the exact proposed ingredient and what remains uncertain. A study link is the start of that discussion.
