FAQ

Frequently Asked Questions

Clear answers to common concerns about compounded GLP-1 providers and pharmacy verification.

You can confirm a pharmacy’s 503A designation through your state board of pharmacy, which licenses and regulates traditional compounding pharmacies. You can also search the FDA’s list of registered outsourcing facilities to see if the pharmacy holds a separate 503B registration. A telehealth provider should publicly name its compounding pharmacy partner so you can verify it independently. Inclusion in the GLP-1 Primer directory does not constitute a medical recommendation or endorsement.
