About Prime

Decline is common.
It is not inevitable.

A member seated in the Prime clinic lounge

A man in his forties should not have to accept thirty extra pounds, a 3pm collapse and a drive that is not what it was. Prime is a private medical practice built for successful men who refuse to accept decline as the price of a full life.

Built for men

Your numbers are personal.
So is your physician.

Whether you start with the compounded vial or the brand-name pen, Prime connects you with a licensed physician in your state who reviews your history and your labs one to one, builds the protocol around them, and reviews it with you every quarter. The care does not stop at delivery.

Physicians, not scripts

Every assessment is reviewed by a board-certified physician licensed in your state. No automated approvals. No call center.

Labs before prescriptions

A baseline metabolic and hormone panel is ordered before any protocol is written, and rechecked every quarter.

Discretion by default

Encrypted records, unmarked packaging, no insurance claims. Nothing leaves our practice without your written consent.

The physicians behind
your protocol.

Board-certified clinicians who wrote the Prime protocol and review every plan personally. Not a call center.
