The verdict
CoreAge Rx takes it on Value Score, 93 to 55 — an est. $99/mo first month, with no teaser step-up baked in. Knownwell isn't out of it: Someone who wants an obesity-medicine clinician they can sit across from, not just a prescription.
CoreAge Rx is also our overall #1 pick across the whole deals ranking — a flat, all-in price on both molecules in all 50 states. That's why it wins here on the score, not just this matchup.

Factor by factor
The six factors behind each Value Score. The orange bar marks the stronger side. See the methodology.
CoreAge Rx
The honest lowest price: both molecules at one flat, all-in monthly rate that never steps up after month one.
Why it's a deal
- Flat, all-in monthly price with no intro-rate step-ups after month one
- Both compounded semaglutide and tirzepatide on one account
- Available in all 50 states
- Straightforward, low-friction cancellation — no lock-in
The fine print
- Not the rock-bottom sticker — a couple of teaser tiers advertise lower month-one rates
- No FDA-approved brand-name option (compounded only)
- Does not yet publicly name its 503A/B pharmacy partner
Knownwell
Knownwell is a weight-inclusive metabolic and primary care company running in-person obesity-medicine clinics in six states alongside a nationwide virtual clinic, prescribing brand-name GLP-1s.
Why it's a deal
- Runs real in-person clinics — California, Georgia, Illinois, Massachusetts, New York and Texas — rather than being a prescription pipeline with an address
- Care is built around obesity medicine as a specialty, with clinicians listed by state rather than pooled anonymously
- A nationwide virtual clinic covers patients outside the six clinic states
- Primary care sits alongside the weight program, so the GLP-1 is not the only thing being treated
The fine print
- Self-pay medication prices are not posted — the cost is discussed after you are in the system
- Brand-name focus means a higher medication bill than the compounded routes elsewhere on this site
- In-person access is limited to six states; everyone else gets the virtual clinic
- Coaching and sleep-health services are advertised as coming soon rather than available
