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 — cheaper teaser tiers exist (Direct GLP lists $65, Ondra $93 on semaglutide)
- No FDA-approved brand-name option (compounded only)
Zera Health
81/100Where the value is
- Compounded semaglutide from $149/mo and tirzepatide from $199/mo, plus a $129/mo microdose option
- Flat pricing — the same monthly cost at every dose as you titrate up
- All-inclusive: medication, unlimited 24/7 provider messaging, and free shipping bundled in
The tradeoffs
- Operates as a technology platform, not the medical provider itself
- Compounded GLP-1s are not FDA-approved (the site discloses this honestly)
