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)
Good Girl Rx
66/100Where the value is
- LegitScript certified
- Multiple formats — injectable, microdose, and ODT pills — for both semaglutide and tirzepatide
- Dispensed by licensed 503A or 503B pharmacies
The tradeoffs
- The advertised rates require twelve months paid up front; billed month to month the same products are $184 and $244, roughly 2.3 times as much
- Every plan is prepaid — the discount exists only on the 3-, 6- and 12-month terms
