About Defy Medical


We specialize in Men’s Health, Women’s Health, and integrative therapies via telemedicine.
Defy Medical’s goal is to treat the whole patient, not just one or two symptoms.
We’ve offered telemedicine care for more than a decade and helped thousands of patients achieve better, happier lives. Our providers are experts in the field of integrative medicine and bring their expertise to you with extended consults and customized care plans.
If you’re tired of traditional health care with incomplete treatment and too little time with providers, Defy Medical is here to help.

Where Does Defy Medical Operate?
Defy Medical is licensed to practice and prescribe in the United States. We offer comprehensive health services via telemedicine in most states throughout the US. We also perform in-office therapies at our clinic in Tampa, FL.
Options for International Patients
Many patients outside the United States seek our expertise, and we provide advice-only consultations for those patients. In an advice-only consultation, a Defy Medical provider will review your lab work, goals, and existing protocols if applicable to provide expertly guided recommendations. You can then take these recommendations to your local provider for more specialized care.
We cannot prescribe and ship medications overseas.
