What this guide covers
FDA-approved means reviewed for a specific product and use
An FDA-approved drug has been reviewed by FDA for safety, effectiveness, quality, labeling, and manufacturing for its approved use. That does not mean every product advertised online with a similar ingredient has the same status.
Unapproved products can create real risk
FDA has warned about unapproved GLP-1 products used for weight loss, including concerns about dosing errors, counterfeit drugs, and active pharmaceutical ingredients from unverified sources.
The supply chain matters
FDA created a Green List import alert to help stop GLP-1 active pharmaceutical ingredients with potential quality concerns from entering the U.S. supply chain. That is a signal to ask direct sourcing questions.

- Counterfeit products may contain too little, too much, or none of the active ingredient.
- Some products may use ingredients or forms that are not the approved product.
- Online sellers may blur the difference between FDA-approved medications and lookalike products.

Questions before you pay
Ask the provider to name the exact product, active ingredient, pharmacy, source, dose form, and whether it is FDA-approved for the discussed use. If the answer is vague, do not rush.
A directory should not hide this distinction
GLP Clinic Finder should clearly separate FDA-approved products, compounded products, and unknown sourcing in future provider profiles so users can compare transparently.
