Dosed AI is your intelligent peptide companion. Whether you're brand new to peptides or a seasoned researcher, Dosed AI handles every step — from generating your personalized protocol to calculating exact injection volumes — so you can focus on results, not math. Dosed AI is not a medical device and does not provide medical advice, diagnosis, or treatment. Consult a licensed healthcare provider before starting, changing, or stopping any peptide regimen. -- AI-POWERED PROTOCOL GENERATION -- Answer a short onboarding survey about your goals, experience level, age, weight, activity level, and health history. Dosed AI analyzes your profile and builds a fully personalized peptide protocol — including which peptides to run, at what dose, at what frequency, and for how long. No generic templates. A plan built around you. Supported goals: - Fat Loss - Muscle Growth - Recovery & Healing - Anti-Aging / Longevity - Sleep & Relaxation - Cognitive Performance - General Wellness -- DOSAGE CALCULATOR -- Enter your vial size and desired dose. Dosed AI instantly calculates your exact injection volume in mL and syringe units, your reconstitution concentration, and the total number of doses per vial. No more guessing, no more conversion errors. -- RECONSTITUTION HELPER -- Never mis-mix a vial again. Enter your peptide amount and the volume of bacteriostatic water you're adding. A live syringe visualization shows exactly how far to draw the plunger for your target dose — displayed in both mL and syringe units. -- CYCLE TRACKER -- Create and track multiple peptide cycles simultaneously. Each cycle card shows real-time progress, days elapsed, days remaining, and a visual progress bar. Log injections with a single tap directly from your active cycle. Supports 4-week, 8-week, and 12-week protocols. -- PEPTIDE DIRECTORY -- A curated reference library of research peptides. Each entry includes: - What it is and how it works - Typical dose and half-life - Best use cases - Beginner / Intermediate / Advanced skill rating - One-tap "Add to My Cycle" to start a cycle immediately Filter by experience level or search by name and category. -- INJECTION LOG & WEEK VIEW -- A scrollable week strip keeps your injection history front and center. Summary rings visualize your weekly adherence at a glance. Every logged injection is timestamped and tied to its cycle — building a complete record of your protocol over time. -- IMPORTANT: MEDICAL DISCLAIMER -- Dosed AI is intended for educational and informational research purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. Peptides referenced in this application are not approved by the FDA for most uses. Always consult a licensed healthcare provider before beginning any peptide protocol, changing your dosage, or making decisions based on information provided by this app. By using Dosed AI, you acknowledge these limitations and assume full responsibility for any actions taken.
