Launch HN: RonanRX (YC S26) – Personalized Peptides and GLP-1s

RonanRX, a Y Combinator-backed startup, offers personalized GLP-1 and peptide prescriptions tailored to individual patient histories, tolerances, and body responses rather than standard one-size-fits-all dosing. The service includes physician-set dose curves, patient-specific adjuncts to manage side effects, and pharmacist verification, with patients initiating care through text consultation at no initial charge. The company addresses common barriers to GLP-1 treatment including inadequate side effect management and high cash-pay prices.
