PepVault: Log doses, draw the right units, see when a vial runs out

Hi Product Hunt. PepVault started from three questions anyone on a peptide or GLP-1 protocol asks every week: did I already take my dose, how many units do I draw from this vial, and when does it run out? So the app does the vial math from your own numbers (mL and syringe units), logs doses with reminders and step-up schedules, rotates injection sites, and shows each vial's run-out date. Weight, bloodwork, Apple Health, Whoop and Oura sit next to the protocol, and PepTalk, an AI advisor, reads all of it when you ask a question. It's a tracker and calculator, not medical advice: it records the schedule you set and never recommends a dose. Free trial, then from $9.99/month. The website's tools are free with no sign-up, if you want to try the math first: https://pepvault.app/lab Feedback very welcome, especially on what you track that we don't.
