Dose-escalators. A flat per-dose price means titrating from 0.25mg to 2.4mg costs the same every month, so the twelve-month number you model on day one is the number you pay.

Oak

83/100

Where the value is

  • $119 semaglutide and $185 tirzepatide — both among the lowest published on this board, and published before the intake rather than after it
  • "ONE PRICE · ALL DOSAGES · NO SUBSCRIPTIONS" — the price does not climb as your dose does, which is where most flat-looking programs quietly get expensive
  • A non-injectable route as well as the two weekly injections: sublingual drops or tablets targeting the GLP-1 pathway

The tradeoffs

  • It publishes three different prices for the same product: $119 in the homepage hero, $167 in the homepage comparison table and on /product, and $190 in the /weightloss comparison table
  • The "$200 OFF — NEW PATIENT OFFER" and "SUMMER SALE — Save up to 60% vs. retail pricing" banners carry no terms, no code and no resulting price anywhere on the site
