Approved, compounded or research-only?
Start with the product
FDA approval belongs to a specific product, formulation and use. A familiar molecule name does not make every product containing it approved.
Compounding can meet a patient's medical need when an approved product does not. Compounded medicines are not FDA-approved and do not undergo the same premarket review.
A seller's “research-only” label does not demonstrate that a product is suitable for human use. Ask a pharmacist what product you have and which label applies.
Read a claim carefully
“Studied” tells you that someone investigated a question. It does not tell you the result, the study quality or whether it involved people. Check the population, the outcome and the limits before accepting a claim.
Quick check
Does the same molecule name mean the same FDA approval?
