Welcome to MD Longevity

Of Greenwich, Connecticut

Ann J Peters, MD, believes the potential for longevity and optimal quality of life is in everyone. The goal of MD Longevity is to help those interested in feeling, looking and living well delay, prevent and even reverse the signs and symptoms of aging. Dr Peters describes, “We strive to restore a youthful endocrine system, countenance and function”

At MD Longevity of Greenwich, Connecticut, our model of medicine is not based on one size fits all. It is personalized medicine tailored to fit each individual’s health needs, taking into account their medical history, family history, their health goals and concerns. Dr Peters treats men’s health issues and women’s health issues as they relate to declining hormones.

Dr Ann J Peters, MD routinely checks hormone levels once her clients start therapy and uses the levels as part of her guide to their ongoing therapy. The bottom line is subjective: how the client feels and functions. She checks for symptom relief - are they more energetic, more fulfilled, have a better outlook on their life and their health; are they happier? Their subjective feedback is correlated with the levels of testosterone, DHEA sulfate, thyroid hormone, pregnenolone, growth hormone, insulin, and cortisol for adrenal status, and estradiol in men and women. Additionally, she monitors progesterone in women. She maintains men and women at their optimal, yet safe, doses of their natural hormones. Accompanying her routine tests are the supporting labs including lipid panels, chemistries, liver and kidney function tests and prostate specific antigen (PSA) in men.

Milton Williams, a 55 year old screenwriter and producer, first saw Dr. Ann J Peters, MD in 2007. He came with a strong family history of heart disease and high cholesterol. His father died at the age of 51 of a heart attack and Williams did not want to follow in his footsteps. On testing and evaluation, Dr. Peters found a high risk of heart disease. Without lifestyle changes comprising proper nutrition, fitness, and preventive intervention with bioidentical hormone optimization, Williams was heading down the same path as his father. His baseline total testosterone level was 320 ng/dL and free testosterone was 12 ng/dL. His thyroid levels were suboptimal; thyroid stimulating hormone (TSH) was 4.1 and both active thyroid hormone levels,  free T3 and free T4, were very near the low range of 2.2 pg/mL and 0.9 ng/dL respectively. His DHEA was also low at 92 and his morning salivary cortisol was high at 20.7, manifesting adrenal distress. His IGF-1 level, which measures his growth hormone status, was only 101 when the optimal is closer to 230 or slightly higher for his age.

Dr. Peters started him on thyroid hormone, both T4 and Triiodothyronine (T3), the most active of the thyroid hormones, combined in one pill he takes on an empty stomach each morning. His therapy includes testosterone which he applies topically to his neck and chest each morning to achieve consistent levels each day. Dr. Peters monitors his estradiol levels to keep blood level ratios of testosterone to estrogen ideal. He also injects growth hormone on an empty stomach before going to bed. Williams also takes adaptogenic herbs to decrease his cortisol levels and, with DHEA added to his regimen each morning, his adrenal status has improved. Today Williams is a different man. He has set his goals to new heights. He is more engaged with life, with his friends and family, and succeeds in his businesses. A follow up exercise stress test and coronary artery scan requested by Dr. Peters shows him in good shape. His cholesterol and blood pressure are normal and he has averted the risk of heart disease.
