Doctor-led medical services include cardiovascular care with inclisiran therapy, hormonal and endocrine optimisation, metabolic and weight management, and GP and preventative care from a female-led team.

Therapies include IV infusion therapy with formulations such as an NAD+ cellular support infusion, a vitamin C nutrient drip, iron infusions and a custom longevity blend, plus NAD+ therapy, red and infrared light therapy at 630 nm and 850 nm, and apheresis. Care is also packaged into three structured longevity programmes: ORIGIN (a weekend reset), ASCEND (30 days) and ZENITH (3 months).
