Build muscle with an AI coach that learns what your body responds best to. myoxin uses your workouts, recovery, progress, and scientific literature to help you train smarter, get stronger, and stop guessing what to change next. Log workouts. Ask training questions. Get weekly analysis and statistics. Let your plan adapt. All in the app, and on WhatsApp too if you prefer. What myoxin does: • A plan that explains its reasoning Every session comes with its why: what your coach changed since last time, and what it is responding to. Clear progression you can follow, not a random AI-generated workout. • Full weekly training analysis myoxin analyzes your workouts, volume, intensity, muscle stimulus, progression, fatigue, and recovery patterns to show what is working, what is stalling, and what should change next. Every Sunday it reviews the week you actually trained and writes the changes straight into next week's sessions, so the analysis becomes a plan instead of a report. The more you train, the more specific the feedback becomes. • AI fitness coach in the app or on WhatsApp Text it. Send voice notes, photos, and videos. Ask what to do in a crowded gym, send a lift video for form feedback, share a restaurant menu for nutrition advice, or send a photo of a terrible hotel gym and get a replacement workout. • 35M+ scientific papers on demand Ask questions about hypertrophy, strength training, recovery, nutrition, soreness, deloads, exercise selection, or programming, with answers grounded in scientific literature and your own training data. • Biology-based muscle stimulus model myoxin tracks how much useful training stimulus each muscle is getting, so you can see which muscles are undertrained, which are progressing, and where you may be adding volume without much return. • Wearable and recovery data integration Connect health and wearable data like sleep, HRV, activity, nutrition, recovery, and body metrics, so your training plan can respond to more than just sets and reps. • Free by design No myoxin subscription. Connect your own Google Gemini API key and your coach runs on it. Disconnect any time. Features: • Fast workout logging built for between sets • Strength training, bodybuilding, hypertrophy, cardio, and gym workout tracking • Set, rep, weight, RIR, warmup, drop set, and failure set logging • Reusable workout templates • Weekly workout split planning • AI workout planner and adaptive training recommendations • Exercise progress charts • Estimated 1RM, tonnage, sets, reps, and trend tracking • Muscle stimulus analytics and muscle heatmap • Custom exercises and favorite exercises • Exercise library for strength, cardio, and mobility • Health and wearable data sync • Track diet, protein, supplements, stress, illness, and alcohol alongside training • AI personal trainer support through text, voice, photos, and videos • Science-backed fitness, nutrition, recovery, and training answers Most workout trackers only record what you did. Most AI fitness apps give generic answers. myoxin is built to close the loop: train, analyze, learn, adapt, repeat. Less random workout generator. Less generic chatbot with gym vocabulary. More like a personal exercise scientist that actually knows your training. Download myoxin and start training with a plan that adapts.

Protocol is the ultimate lab app for your peptide cycles — a premium iOS tracker for people who treat their stack seriously. Log every injection in micrograms, ride the streak, and keep your reconstitution, injection technique, and safety guides one tap away. WHAT YOU CAN DO Build your stack - Add from a curated library of 25+ compounds: BPC-157, TB-500, Tirzepatide, Cagrilintide, Retatrutide, Semaglutide, GHK-Cu, CJC-1295 (no DAC), Ipamorelin, Sermorelin, Tesamorelin, NAD+, MOTS-c, Humanin, SS-31, AOD-9604, Pinealon, Selank, Semax, DSIP, PT-141, KPV, Thymosin alpha-1, VIP, SLU-PP-332. - Configure each entry: dose amount in micrograms, milligrams, or IU; frequency (daily, every other day, twice daily, post-workout, weekly, custom); a color tag; private notes. - Add custom compounds outside the library. Edit or pause any entry at any time. Log doses in one tap - The Today screen shows your full stack. Tap "Log" — the dose is recorded with the right amount, unit, and timestamp. - Mistapped? Undo the last log instantly. - A day badge shows how many doses you've taken for each peptide today (×1, ×2, ×3). Streaks and history - Streak counter on Today and Profile counts consecutive days with at least one dose. - "This week" and "All time" totals sit next to the streak. - Pull to refresh; everything syncs to the cloud the moment you tap. Reminders that match real protocols - Per-peptide reminders: pick times of day, days of week, AM/PM windows, post-workout cues. - Native iOS notifications, respectful of Do Not Disturb and Focus modes. - The Notifications screen logs every reminder fire and streak milestone in one feed. Built-in safety and how-to guide - 10 in-app chapters written for the peptide-curious and the long-cycle stacker: • Important disclaimer — what this app is and isn't • Your first cycle — where to start • Reconstitution — mixing lyophilized peptides safely • Injection technique (subQ) in 6 steps • Storage & shelf life — lyophilized vs reconstituted • Side effects — common, rare, and red flags • Stacking & cycling — combinations that make sense • Bloodwork to monitor — what to test and when • Sourcing & purity — how to verify what you're injecting • Legal status — know what's allowed where you live Tailored from day one - Onboarding asks two questions: what are you here for (recovery, longevity, performance, GH, cognitive, metabolic, sleep, sexual, immune, skin, weight loss) and your experience level (new, some experience, advanced). - Library and protocol suggestions adjust accordingly. Edit goals & experience anytime from your profile. Profile and identity - Display name, handle, bio, avatar. - At-a-glance stats: total doses logged, current streak, active goals. - Sign in with Email or Google. Privacy-first — no social feed, no public timeline, no follower count. WHAT'S INTENTIONAL - No ads, no social feed, no in-app purchases inside the tracker. - Your data stays yours. WHO IT'S FOR - People running 1–5 compounds at a time who keep their dose log in Notes and forget which vial they're three days into. - First-cycle users who want a clean reference for reconstitution and injection technique before they self-experiment. - Long-cycle stackers who want streaks, weekly volume, and full historical doses on tap. DISCLAIMER Peptide is a tracking and reference tool, not a medical device. Nothing in the app is medical advice or a prescription. Consult a qualified physician before starting any protocol.
