You have two paths: book an appointment with one of the 326 NPI-verified providers in Boston listed on this page, or complete an online telehealth visit and have medication shipped to you. Either way, a licensed provider will review your health history to determine whether semaglutide or tirzepatide is appropriate.
Costs vary by clinic and medication. Brand-name GLP-1s can run $1,000+ per month without insurance, while clinic weight-loss programs and telehealth plans frequently offer more affordable monthly pricing. Contact clinics directly for current rates.
Every listing is sourced from the CMS National Provider Identifier registry and matched to a weight loss, obesity medicine, bariatric, or endocrinology specialty. Confirm current GLP-1 availability with the clinic before booking.
