Longevity medicine with a physician in the room.

MYST is Dr. John Sosa's concierge practice. Before anything is prescribed, your intake runs through the safety rules he wrote, and he reads what they flag. If a therapy is wrong for your history, it never even shows up as an option.

About the founder

Dr. John Sosa

Dr. Sosa started MYST after watching concierge medicine drift into subscription vitamin sales. He is the founder and chief medical officer. He wrote the clinical rules this platform screens against, and the cases those rules flag land on his desk, where he reviews them personally.

That standard is built into the software. If a therapy is not right for your history, MYST will not sell it to you.

Questions

Frequently asked.

What is MYST Medical?

MYST Medical PLLC is a physician-led concierge longevity practice founded by Dr. John Sosa. Members get a physician who actually reviews their history, a clear plan, and direct access to the care team. One monthly membership covers it; there is no per-visit bill.

How does the intake and screening work?

Every membership starts with a structured clinical intake. A rules-based screening maps your answers against each therapy's safety criteria, and a physician personally reviews anything the screening flags. Nothing is prescribed on autopilot.

Do you take insurance?

No. MYST is a membership practice, which keeps treatment decisions between you and your physician and keeps pricing flat. Labs and medications are offered at member rates.

Which states do you serve?

Availability depends on state licensure and is expanding. Tell us where you are when you sign up and we will confirm whether we can treat you today or notify you the moment we can.

I run a clinic. Can I use the MYST platform?

Yes, that is exactly what the clinic partnership is for. MYST provides the intake, screening, provider console, and fulfillment workflow so your clinic can run compliant telehealth programs under your own brand. Start with the clinics page.

I'm a physician. How do I join the network?

We onboard licensed physicians who want to practice longevity medicine with real clinical guardrails. Share your details on the physicians page and our team will reach out to talk scope, states, and schedule.
