Prime Doctor RX
What we like
- Every plan is priced on the homepage before you start, with month-to-month and 12-, 24- and 52-week prepaid rates for each drug
- Names its prescribing medical group, OpenLoop Healthcare Partners, PC
- Offers compounded semaglutide and tirzepatide injections plus a daily oral semaglutide tablet

- Month-to-month plans can be canceled at any time, and refunds can be requested for unused future periods
- Also runs testosterone and enclomiphene programs for eligible men, with the hormone-care state list published
Watch-outs
- The '$179/mo' headline is the 52-week prepay average, paid as one $2,327 charge; month-to-month semaglutide is $249
- Plans are charged every 4 weeks, so month-to-month billing comes to 13 charges a year, not 12
- Ending a prepaid plan early can reprice the months you used at the higher month-to-month rate
- No dispensing pharmacy is named anywhere on the site
- No LegitScript certification, and no Trustpilot profile or other third-party reviews could be found
- Weight-loss availability by state is not published; it is confirmed during intake
- No phone number is published on the site; support is by email and an on-site chat widget
- Product cards never say compounded or brand-name; only a footnote says compounded medications are not FDA-approved
