Eligibility and questions

Who this is for.

Catalyst members 18 and over who want medical supervision behind a body-composition goal. Eligibility is decided by a licensed provider after your labs — not by this page.

Not a fit if you are pregnant, breastfeeding or planning pregnancy; under 18; or have a history your provider flags during review, including certain thyroid, pancreatic or cardiac conditions.
Do I have to be a Catalyst member?+

Yes for the member rate. The programs themselves are open to anyone Apex MD can treat in your state, at the standard rate.

What actually happens at the visit?+

A video consultation with a licensed provider: your history, a lab order, and a plan. Labs are drawn locally, and your provider reviews them before anything is prescribed.

Are these medications FDA approved?+

Personalized and compounded formulations are not FDA-approved products and are not reviewed by the FDA for safety or effectiveness. They are prescribed by a licensed physician for you specifically, using protocols informed by published clinical research.

Does my trainer see my medical information?+

Only your body composition results, and only if you give written consent. Your medical records stay with Apex MD; Catalyst Fitness never receives them.

Can I cancel?+

Yes. Programs are month to month and you can stop at any time by messaging your provider.

Ten minutes online.
