Codex is a science-backed men’s health program created by Dr. Peter Marta, a board-certified physician and surgeon with more than two decades of experience. Combining conventional medicine with evidence-based integrative care, Codex is designed to help men address changes in health and vitality after 40. Its personalized approach focuses on concerns including low energy, sexual function, declining muscle strength, weight gain, and hormonal imbalances.

The program begins with a health assessment and a 45-minute consultation to discuss each patient’s goals and needs. Dr. Marta then develops an individualized plan, supported by regular check-ins and adjustments over time. Services include testing and therapies, including FDA-approved testosterone optimization, intended to support hormone health, sexual vitality, strength, energy, and metabolic health. Codex also offers resources and supplements, with results and patient experiences featured on its website. Based in Paramus, New Jersey, the practice invites men to schedule appointments and pursue tailored support for their health and well-being as they age.
