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
