KairoRx is a telehealth brand launched in 2026 that lists compounded semaglutide and tirzepatide alongside peptide, hormone and longevity treatments. Its pricing page shows semaglutide at $49 for the first month, then $199 a month, and tirzepatide at $99, then $349 a month. The online form ends with a promise of follow-up rather than a checkout, and the company does not name its medical group or pharmacies.
