GoKawiilWeekly-equivalent semaglutide dosing extends lifespan in aged female mice, Berkeley study finds
Researchers at UC Berkeley gave 20-month-old female mice daily low-dose subcutaneous semaglutide, the active ingredient in drugs like Ozempic and Wegovy, and compared them with saline-treated and calorie-restricted counterparts. Over months of treatment, the semaglutide group showed slowed markers of aging and, in a full lifespan cohort of about 80 mice, longer survival than untreated controls.
