PreventiveMD

Cost-first shoppers who want compounded GLP-1s from $83/mo all-in, with brand upgrade paths.

Reasons to consider it

  • Compounded semaglutide from $83/mo and tirzepatide from $97/mo, billed as one all-in monthly price
  • Brand Wegovy, Zepbound, and Foundayo (oral GLP-1) available on the same platform
  • US-licensed provider reviews requests within 24 hours — no video visit required

What to weigh up

  • Both figures are 'as low as' rates and the qualifying term is not published anywhere — the checkout is gated, so whether $97 is month-to-month or a multi-month prepay cannot be established before signing up
  • Brand-name routes are priced separately and do carry a fee: $49/mo membership plus medication from $149/mo for Foundayo and Wegovy, from $299/mo for Zepbound
  • No state count is published, and a state-variant waitlist implies some states are unserved

Knownwell

Insured shoppers who want an obesity-medicine specialist overseeing brand-name GLP-1 care, with published self-pay drug prices as a fallback.

Reasons to consider it

  • Co-founded and clinically led by Dr. Angela Fitch, a named, credentialed obesity-medicine specialist (Chief Medical Officer)
  • Prescribes branded FDA-approved GLP-1s across the current class (Wegovy, Zepbound, Ozempic, Saxenda) plus orforglipron/Foundayo
  • Publishes a self-pay price for every drug and dose, from $149 a month for the Wegovy pill

What to weigh up

  • Brand-name only, and the price rises with the dose: the Wegovy pill runs $149 to $299 a month, the Wegovy pen $349, and Zepbound $299 to $449
  • Those are medication prices; without insurance, knownwell's own visits cost $299 for the first and $149 for each follow-up
  • In-person care is limited to five states (Texas has primary care in Plano only), so most of the country can only use the virtual clinic
