About Defy Medical

Defy Medical is a long-running telehealth clinic, best known for hormone replacement, that also prescribes GLP-1 medications for weight loss. It offers semaglutide and tirzepatide as weekly injections plus oral disintegrating tablets (ODT) and liquid drops, and liraglutide as a daily injection. The drops and ODT forms help patients avoid self-injecting or get treatment where injectable shipping is restricted. Care includes in-depth consults and comprehensive blood testing, with mobile phlebotomy. Medical director is Dr. Justin Saya. GLP-1 pricing and state coverage are not published online.
