Vitality Medical PNW
Vitality Medical is a single-provider Lynnwood practice built around hormone, peptide and performance medicine, led by Erik Marks, DNP. It names its molecules rather than its categories: sirolimus, quercetin, SS-31, sermorelin, GHK-Cu, methylene blue and NAD+ each get their own page. Semaglutide and tirzepatide weight programmes and bioidentical hormone therapy sit alongside.
