Curve
63/100Where the value is
- Offers both compounded semaglutide and tirzepatide, with every dose priced the same so cost does not rise as you titrate up.
- LegitScript-certified (seal #51079066) and names both its 503A compounding pharmacy, VialsRx, and its provider network, Beluga Health.
- Transparent tiered pricing with a real month-to-month option; consultation, medication, and free expedited shipping included, no membership.
The tradeoffs
- Very new (2026 launch) with a thin track record; the site still shows a Webflow template credit and a leftover Cora reference in its Terms.
- The cheapest headline rates ($99 semaglutide / $135 tirzepatide) require a 12-month prepay; true month-to-month is $175 and $225.
Next Vial
63/100Where the value is
- Names its compounding pharmacy partner explicitly (Manifest Pharmacy, Greer, SC)
- Genuine LegitScript verification link found in the footer
- Explicit 44-state coverage list published in the FAQ
The tradeoffs
- Starting price is blended/generic ($249.97/mo) and not broken out by drug or dose tier anywhere public
- No individual medical director named
