The better fit depends on what is included in your quote. A lower advertised price can require prepayment, apply to a starting dose or leave out a separate fee.

Arc-1

Shoppers starting on a low dose who are comfortable with a price that rises as the dose goes up.

Reasons to consider it

  • Each dose has its own price in the cart, so you can see what moving up will cost
  • Free consultation and free shipping, with no separate visit fee
  • Named founder physician (Dr. Todd Stearns)

What to weigh up

  • Prices rise steeply with the dose: semaglutide goes from $199.99 to $549.99 a month
  • The tirzepatide product page says 'starting at $149/month', but the lowest dose in the cart is $199.99
  • No compounding pharmacy is named and no state list is published

FormidableMD

Patients in its four covered states who want physician-led care and will confirm how long each prescription lasts before comparing costs.

Reasons to consider it

  • Publishes an actual dose-by-dose price table for both semaglutide and tirzepatide, rather than a single 'starting at' figure
  • Boutique physician-led practice with real brick-and-mortar roots, bundling labs, HRT/TRT and urgent care
  • FSA/HSA eligible for consultations and services

What to weigh up

  • The drug prices are per prescription, without a published supply length, so a reliable monthly medication cost is not available
  • Visits cost extra: $199 initially and $99 for follow-ups
  • No compounding pharmacy is named
