Visit InstaRXThe verdict
CoreAge Rx edges out InstaRX on the Rx-Readiness Score, 95 to 64 (A vs C). Working moms who want a decision, not a research project — flat pricing, both semaglutide and tirzepatide, and no scheduled video visit to book around work and pickup.
InstaRX is still a genuine option — a flat-price compounded shop — $179/mo semaglutide, $259/mo tirzepatide, same price at any dose — though the site doesn't itemize what's actually bundled into that number. Weigh the six readiness factors below against your own priorities.

CoreAge Rx
Ranked #1 · Grade A
What we like
- Flat monthly price that stays put through titration — no dose-scaling surprise on your busiest month
- Both compounded semaglutide and tirzepatide on one plan, so you're not re-signing to switch
- Async, no-video intake and all-50-states coverage — start it during a lunch break
The caveats
- Not the rock-bottom sticker price — a couple of teaser tiers elsewhere start lower
- Compounded only — no FDA-approved brand option
- General metabolic program, not a boutique concierge service
InstaRX
Ranked #32 · Grade C
What we like
- Both molecules' flat prices visible directly on the treatments page, no intake required
- Same price at any dose — no escalation surcharge as titration increases
- 680+ reviews at an 'Excellent' rating claimed on-site
The caveats
- The homepage doesn't itemize what's bundled into the flat price (consult, shipping, supplies)
- No brand-name (FDA-approved) option and no oral form
- No published time-to-first-dose or statement on whether a video visit is required
