Peptid.io vs Stack

peptid.io is an educational research companion and private log for adults (18+) who take an evidence-first approach to their body — peptides, GLP-1 protocols, and now daily nutrition, all in one place. PEPTIDES & PROTOCOLS • Build a protocol as a stack — several compounds in one cycle, each with its own dose. • Log doses in two taps with an injection-site map, mood, and notes. • See a clean dashboard: next and last dose, cycle day, and adherence streaks. • Watch estimated compound levels rise and fall over time from your logged doses. • Manage vial inventory and calculate reconstitution (units to draw). NUTRITION TRACKING (NEW) • Set calorie and macro goals manually, or from a quick fitness-goals quiz. • Snap a photo of your plate for an instant calorie and macro estimate. • Search a large US food database, or quick-add anything in seconds. • Track daily and weekly totals with a clean calorie ring and macro breakdown. LEARN & ASK • A clearly-cited library grades the evidence behind each compound — from strong human data down to preclinical. • Read and write community reviews. • Ask an educational AI coach about mechanism, evidence, timing, and storage — it knows your goals and current protocol for context. peptid.io is for education and personal tracking only. It does not diagnose, prescribe, sell, or ship anything, and is not medical advice. Always consult a qualified healthcare professional. 18+. — Terms of Use (EULA): https://peptidio.vercel.app/legal/terms Privacy Policy: https://peptidio.vercel.app/legal/privacy

Stack is the all-in-one tracker for peptides, GLP-1 medications, and TRT protocols. Log every injection, build custom dosing schedules, track your progress, and keep your full history organized in one private place. Built for adults working with a prescribing healthcare provider, Stack replaces scattered notes and spreadsheets with a simple, consistent system you control. You enter your own values (peptide name, dose, schedule, and sites) and Stack keeps them organized, reminds you, and shows your progress over time. FEATURES • Custom Protocols & Stacks — Build your own multi-peptide protocols with flexible schedules (daily, weekly, every X days, or custom). Run multiple stacks at once, each clearly organized. • Smart Dose Logging — Log every injection in seconds and see what's due today on your Home screen and calendar. A daily streak keeps you consistent. • Reconstitution Calculator — Take the guesswork out of mixing. Enter vial amount, diluent volume, and target dose to get the exact mL or insulin-syringe units to draw. • Vial & Refill Tracking — Set how much each vial holds, watch it deplete with every dose, and refill in one tap. A tap-to-flip ring shows the exact percentage remaining. • Injection Site Tracker — Rotate sites with an interactive body map that remembers your recent spots, so you can avoid reusing the same area. • Apple Health Sync — Pull in weight, BMI, resting heart rate, HRV, sleep, steps, active energy, blood pressure, respiratory rate, body fat, lean mass, and VO2 max to see the full picture. • Progress Photos & Compare — Capture progress photos and view them side by side with weight and date overlays. Hide weight for privacy, then share a branded comparison. • Meal Scan — Snap a photo of your meal to estimate macros and keep nutrition alongside your protocol. • AI Assistant — Ask questions about your active stacks and protocols in a private chat built into the app. • Metrics & Insights — Clean charts and stats show how your protocol is trending over time. • Home Screen Widget — See your next dose and stay on track without opening the app. • Shareable Protocol Card — Generate a clean, branded card of your active protocol to save or share. PRICING Stack requires a subscription to unlock the full experience. IMPORTANT Stack is a personal record-keeping and organization tool for informational purposes only. It does not provide medical advice, diagnosis, or treatment, and is not a substitute for professional care. Always consult a qualified healthcare provider before starting, changing, or stopping any medication or protocol.
