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.

Open Water Rx

Shoppers who want published monthly all-dose injection prices and separate oral options.

Reasons to consider it

  • One-month injection plans have no dose-based price increase
  • Clinical review, medication if prescribed, shipping and follow-up are included
  • Oral semaglutide and tirzepatide have separate published prices

What to weigh up

  • Multi-month plans require prepayment; confirm the total before buying
  • Cancel at least 72 hours before the next billing date
  • The homepage says no charge before approval, while its cancellation policy describes payment at checkout and a refund if declined

NuBloom

Women who want a physician-founded, whole-person GLP-1 program in one of the 49 states it covers.

Reasons to consider it

  • Prices published up front, month to month: semaglutide $149/mo, tirzepatide $279/mo, microdose tirzepatide $249/mo
  • Founded and medically led by a named physician (Dr. Marianne Pinkston Mueller)
  • LegitScript certified, with appointments through Qualiphy, also LegitScript certified

What to weigh up

  • The compounding pharmacy is never named, only 'a state-licensed sterile compounding pharmacy partner'
  • Each plan shows one monthly price with every dose listed, but the site doesn't say the price holds as your dose goes up
  • The semaglutide-plus-coaching program is listed at $599/mo on one page and $499/mo for three months on another
