Dr. Peter Marta

Dr. Peter Marta (affectionately called Dr. Pete) is board-certified physician and surgeon and creator of Codex for Men, a revolutionary approach that combines the precision of conventional medicine, the nuance of functional medicine, with ground breaking therapies and lab testing to optimize men’s hormones and health through their later years. Through Codex and testosterone optimization, his patients increase energy, restore sexual vitality, rebuild muscle strength, boost cognitive clarity and improve metabolic health. Codex emerged from personal trials, insights gained during two decades in surgery, and a desire to identify root causes and push beyond conventional medicine’s “quick fixes.” Integrating his surgical expertise with a deep understanding of conventional and functional medicine, Dr. Pete brings warmth, wit, and an eye for detail to his work. Known for his compassionate and down-to-earth style, he sees his practice as an art form—balancing cutting-edge science with personal, tailored care. A graduate of Rutgers University with a master’s degree in biology with a focus on molecular biology, a medical degree from UMDNJ and a surgical residency with board certification, Dr. Marta is published in major medical journals and has over 20 years of medical experience.
