CoreAge Rx
94/100Where the value is
- Flat all-in monthly price — no intro rate that silently triples after month one, so the modeled annual cost is the real cost
- Both compounded semaglutide and tirzepatide on one account at published prices
- Available in all 50 states — no coverage gamble
The tradeoffs
- Not the rock-bottom sticker price — 30 of the 381 priced semaglutide programs we track list a cheaper figure, though most attach a term or a step-up that CoreAge does not
- No FDA-approved brand-name option (compounded only)
Willow
49/100Where the value is
- Oral tablet formulations of both semaglutide and tirzepatide, priced identically to the injectable versions ($299/mo and $399/mo respectively) — a genuine format choice most compounded-drug competitors don't offer
- Month-to-month billing with no prepay or annual term required to get the advertised rate
- Named physician team publicly listed, including Chief Medical Officer Dr. Michael Green, MD, plus 11+ other credentialed MDs/DOs
The tradeoffs
- Only 34 states served — notably narrower than WeightlessRx's 49-state footprint; residents of the other 16 states plus DC are excluded
- Site states medication cost 'varies by dosage and prescription' but never discloses what a higher maintenance dose actually costs beyond the $299/$399 starting figures
