PeptideCore: Shot & Stack Log

The most complete protocol tracker for serious GLP-1 and peptide users. Track Ozempic®, Wegovy®, Mounjaro®, Zepbound® — or any peptide stack — with pharmacokinetic curves, a stack-interaction checker, and a citation-backed library no other tracker offers. PeptideCore is the private, on-device companion for GLP-1 patients, peptide stackers, microdosers, and biohackers who want a clean visual record of every shot, dose, and side effect. No ads. No data sold. No bro-science. Built by an iOS engineer who tracks their own protocol. FREE TO USE Log every dose, rotate injection sites, run the reconstitution calculator, and browse the peptide library — free, no account required. PeptideCore Pro is optional. WHAT YOU GET WITH PRO • Estimated medication-level curve. See how semaglutide, tirzepatide, retatrutide, or any peptide with a known half-life decays over the past week — with peak and trough markers. • Visual injection-site map. Front and back body view with 14 sites. Each site color-codes by days since last use so you rotate intelligently. • Dose-coded weight chart. Your weight line is colored by current dose tier so the weight loss response to your Mounjaro® or Wegovy® titration is visible at a glance. • Reconstitution calculator. Forward (dose → units), reverse (target draw → BAC water), and multi-peptide blend modes. Supports U-100, U-40, and tuberculin syringes. • Curated peptide library. 25+ entries with typical dose, half-life, route, and a tap-through PubMed citation. Covers BPC-157, TB-500, CJC-1295, Ipamorelin, MOTS-c, GHK-Cu, PT-141, Tesamorelin, and more. • Stack interaction checker. Flags overlap between active compounds with severity grading and PubMed-linked citations. • Inventory tracking. Vial-by-vial stock with expiry dates, reorder reminders, lot numbers, and cost per dose. • Live Activity countdown. Your next shot lives on your lock screen and Dynamic Island. • Apple Health integration. Pulls weight, HRV, sleep, and resting heart rate to correlate with your protocol. • Private on-device AI. Apple Intelligence flags adherence trends, symptom patterns, and site rotation balance — without sending your data anywhere. • Share card export. Render a branded progress card to celebrate weekly wins.
