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)
Zeuss
63/100Where the value is
- Genuinely no-subscription billing confirmed in its own FAQ ('no recurring charges or automatic refills') — patients pay per order, not a locked recurring plan
- LegitScript certified, with the badge and verification link displayed on the homepage
- States it 'partners exclusively with 503A and 503B state-licensed compounding pharmacies'
The tradeoffs
- Both $125 and $175 are 'starting at' prices with no disclosed dose (mg) or confirmation the price holds at higher/titrated doses
- No compounding pharmacy is named, only 'licensed partner pharmacy'
