Editor, metabolic health
Guides and research answers on GLP-1s, metformin and rapamycin, written to be read in one sitting.
Marisol Keane edits LongevityGLP1 and writes most of its drug guides and research answers. Her beat is the question a reader asks before a first appointment: what the label says, what the trials used, and what that means for the next ten years rather than the next ten pounds. She starts every guide from the FDA label or the published trial, puts the starting dose and the monthly cost near the top, and rewrites anything a tired reader would have to read twice. She covers compounded and brand semaglutide and tirzepatide, the oral options, low-dose prescribing, metformin and rapamycin.
