CoreAge Rx vs Open Water Rx
Two GLP-1 providers, one scoreboard. We put CoreAge Rx and Open Water Rx head-to-head on the published Brief Score — the same six factors, scored the same way.
CoreAge Rx
The verdict
CoreAge Rx takes this head-to-head.
CoreAge Rx scores 94 to 66 on our six-factor Brief Score — One price on both molecules that does not climb as you titrate — but the headline $99 and $149 are annual-plan rates, paid in full up front.
That doesn't make Open Water Rx a bad call — it's best for readers who want one flat, all-inclusive monthly price that does not rise with the dose. Weigh the six factors below against your own priorities before you decide.
Why CoreAge Rx leads: it's our #1 here — one flat, no-step-up price on both molecules, nationwide, and the steadiest line on our tracker.
Assume any provider we list may compensate us — we may earn a commission, at no cost to you. It never changes the Brief Score.

CoreAge Rx: Headline unchanged for a third straight cycle. The $99 and $149 are the 12-month prepay rates; CoreAge publishes no month-to-month price.
Open Water Rx: Re-read on the provider's own pricing page on 24 September 2026: compounded semaglutide is $169 and tirzepatide $219 for one month, the same at every dose, with shipping and the clinician review included. That is lower than the figures we first carried, so the direction is down. Three- and six-month plans lower the monthly cost further.
