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.
