Pricing
CoreAge Rx
Oak
Hero + product card: 'Semaglutide from $119' / 'Most Affordable Semaglutide As low as $119 /mo'. Old code OAKNEW50 no longer on site; a '$200 off — new patient offer' is advertised with no published terms or resulting price (quiz-gated), so promo price is not published. Site is internally inconsistent elsewhere ($133 meta description, $167 compare table, $190 on /weightloss) — hero pricing matches
Hero + product card: 'Tirzepatide from $185' / 'Most Popular Tirzepatide As low as $185 /mo'. Same flat 'One price · All dosages · No subscriptions' model; $200-off new-patient offer advertised without published mechanics — final checkout price quiz-gated, not published.
