    Led by Dr Martin Galy, 23MD approaches longevity as medicine should be practised: clinically, personally, and over time. Our work is anchored in hormonal and metabolic medicine, supporting men and women through the years when biology begins to shift: perimenopause, menopause, andropause, metabolic change, fatigue, weight resistance, and loss of vitality.

    The Longevity Programme is our flagship integrated offer: every discipline (BHRT, metabolic, weight, cardiovascular, cognitive) coordinated under a single physician. Quarterly review, continuous biomarker tracking, and concierge access between consultations.

    Bioidentical hormone replacement, prescribed by a qualified physician following comprehensive testing and monitored through scheduled follow-up, is well-tolerated and effective for appropriate candidates. Every protocol is individually titrated and reviewed.

    Bioidentical hormones are molecules identical in chemical structure to the hormones your body naturally produces — such as oestradiol, progesterone and testosterone. They are typically derived from plant sources (yam or soy) and then formulated to precisely match your own biochemistry. Because their structure is the same as your endogenous hormones, they bind to the same receptors and are metabolised in the same way, allowing us to titrate to your individual physiology rather than to a fixed category dose. At 23MD, bioidentical hormones are always prescribed by a qualified doctor following comprehensive bloodwork and reviewed on a scheduled basis.

    Adults aged 35–65 who notice the early signals of decline — fatigue, sleep disruption, weight resistance, mood shifts, lower performance — and those who want to stay ahead of them. Patients are typically professionals, founders and executives.

    Most patients report measurable improvements in energy, sleep and cognition within 8–12 weeks. Full benefits emerge over 6–12 months as protocols are refined.
