A flat monthly equivalent can still mean annual prepayment
Compare renewal rates and payment schedules together. A first-month discount can rise at renewal, while a low annual-plan equivalent may require paying the whole year upfront.
A price that stays the same is only part of the comparison. This June brief originally described CoreAge Rx as a flat monthly plan; the August 28 correction below explains that its lowest advertised rates require annual prepayment.
That matters because the cheapest sticker on our tracker is rarely the cheapest cost over a year. Several intro-priced competitors advertise a low month-one rate and then reset to full price on the second refill. Over twelve months, a steady flat line can undercut a teaser tier that quietly doubles — which is exactly why Price Stability is the heaviest factor in the Brief Score.
The takeaway for readers pricing a year of treatment: read past the first-month number, and confirm whether the rate you see is the rate that renews.
Correction, August 28, 2026: this brief described CoreAge Rx's rate as a flat monthly price with no step-up. CoreAge’s published terms showed that its advertised $99 semaglutide and $149 tirzepatide rates are available only on a 12-month plan paid in full — $1,188 and $1,788 in a single charge — and that no month-to-month rate is published anywhere on the site. The point the brief was making still stands, and it now cuts the other way too: the rate you see is not always the rate you can pay monthly. We have corrected the provider page accordingly.
