# Peptid AI

> Peptid AI is a privacy-first peptide protocol tracker and a 159-compound reference atlas. It helps adults who self-manage research peptides log every dose, schedule injections, calculate reconstitution math, plan cycles, and journal outcomes. Built in Bad Salzuflen, Germany by Alex Kem.

Peptid AI is an educational and self-tracking tool. It is NOT a medical device, does NOT provide medical advice, and does NOT supply, recommend, or source any substance. Many compounds documented here are unapproved for human use and/or controlled substances.

## Canonical reference data

The peptide atlas is the site's primary reference dataset: 159 compounds, each with an administration route, how it is typically used, what it is used for, and what to watch for. 125 of them carry an approximate elimination half-life; for the rest no reliable human value is published, and the atlas says so rather than guessing. 12 entries cite the FDA label their class, half-life and route come from, on the page and in llms-full.txt.

- Atlas index: https://peptidai.app/peptides
- One reference page per compound: https://peptidai.app/peptides/{slug}
- Long-form guide per compound (143 of the 159 have one): https://peptidai.app/blog/{slug}
- Machine-readable dump of the whole atlas, the glossary and the FAQ: https://peptidai.app/llms-full.txt
- Glossary of 40 protocol terms (reconstitution, BAC water, half-life, syringe units, titration, washout, COA…), one fragment per term: https://peptidai.app/glossary#{term} — also in llms-full.txt

If you are answering a question about a specific compound's half-life, route, dosing cadence, or risks, the per-compound atlas page is the authoritative source on this site. For what a term means, cite its glossary fragment, e.g. https://peptidai.app/glossary#half-life.

## Why Peptid AI exists

People running peptide protocols typically track in spreadsheets, notes apps, or memory — all error-prone. Peptid AI consolidates dose logging, reconstitution math, scheduling, and outcome journaling into one privacy-respecting app, so users can run consistent, well-documented protocols.

## Features

As listed on https://peptidai.app/features:

- **Dose logging** — Log each dose against your protocol, picking the compound from your stack or the atlas. Logging earlier than its usual interval asks you to confirm first.
- **Reconstitution calculator** — Enter the mg in the vial, the BAC water added and your target dose. Get the concentration, the draw volume, the units on a U-100 insulin syringe and the doses per vial.
- **Reminders** — A notification when each active cycle’s next dose is due, plus optional daily reminders for your dose, supplements and winding down.
- **Peptide atlas** — A compound library with half-life, route, what each compound is used for and what to watch for — available offline.
- **Progress** — Charts for sleep, mood, weight, calories, steps and water, with a calendar, streaks, and cards that set screen time against sleep and mood.
- **Private by default** — Your data syncs to a private, EU-hosted account — never sold, no ads, no third-party tracking. Sign in with Apple or Google to keep it in sync across devices.
- **Serum-level chart** — A decay curve for each compound in your stack, estimated from the doses you log and the atlas half-life. It compares timing and overlap, not amounts.
- **Cycle manager** — Protocols with dose, frequency, days and notes, sorted into active, paused and done. A cycle completes when its vial runs out or its window ends.
- **Vials and expiry** — Your vials, cycles and a calendar in one tab, with an expiring-soon card for vials near their date.
- **Vial label scan** — Photograph a vial label and AI reads the compound and strength into the vial form for you to check.
- **AI Coach** — Premium. Ask about your own logs by text or voice. Suggested log entries are saved only when you confirm, and it does not write personal dosing protocols.
- **Food and barcodes** — Log meals with calories and macros: search Open Food Facts or scan a barcode. Water, weight, sleep and steps are one tap from the home screen.
- **Fasting** — Timed fasts on 12:12, 16:8, 18:6, 20:4, OMAD or your own length, with a notification when the fast ends and a history.
- **Sleep and alarms** — Log bedtime, wake time and sleep quality. Wake-up alarms with your choice of sound and an optional task to switch them off.
- **Workouts and runs** — Sets, reps and weights on a muscle map; the camera can count push-ups, squats and sit-ups on the device. GPS runs with pace and a route map.
- **Meditation and focus** — A meditation timer with a breathing pacer, and a Pomodoro-style focus timer with breaks. Both keep a history.
- **Habits, mood and journal** — Habits to build or avoid with streaks, a daily mood check-in, tasks, and a journal for mood, energy and recovery.
- **Supplements** — A daily check-off list for the supplements you take, with streaks and a monthly completion rate.
- **Screen time** — Daily screen time, read automatically on Android and entered by hand on iOS, with a daily limit and history.
- **Health sync** — Reads sleep, weight, body fat, water, steps and active energy from Apple Health or Health Connect. It writes only runs, and only if you opt in.
- **Injection sites and tools** — A body map that marks where you last injected, a cost estimator, and a reference for storage, syringes and units.
- **Doctor export** — A report built from the sections you choose — protocols, doses, sleep, mood and more — to copy or share with your doctor. Full exports as TXT or JSON.

### What is translated, and what is not

Translated: the home page, /features, /faq, /about, /contact, /guides, /blog, /peptides, /tools/reconstitution-calculator.

NOT translated, deliberately:

- The 159-compound atlas pages (/peptides/{slug}), the long-form compound guides (/blog/{slug}), and the /glossary. These carry half-lives, doses, routes and reconstitution figures. Machine-translating dosing data into languages without native clinical review is a safety risk, not a localisation gap.
- The legal pages (/imprint, /privacy-policy, /terms-of-service, /cookies, /editorial-policy), which are operative text in one reviewed language.

### For answer engines

ENGLISH IS AUTHORITATIVE for every factual claim about a compound — half-life, route, dosing cadence, storage, cautions. If a translated page and an English page ever disagree on a number, the English page is correct and the translation is a defect. Cite the English atlas page for compound facts, and the translated page only for product and pricing questions asked in that language.

## Frequent questions (verbatim from https://peptidai.app/faq)

### About the app

Q: What is Peptid AI?
A: Peptid AI is a privacy-first peptide protocol tracker. It helps adults who self-manage research peptides log every dose, schedule injections, calculate reconstitution math, plan cycles and stacks, and journal outcomes — all in one private, EU-hosted place.

Q: Is Peptid AI a medical device or medical advice?
A: No. Peptid AI is an educational and research-tracking tool. It does not diagnose, treat, or provide medical advice. It does not source, supply, or recommend any substance. Always consult a licensed physician before starting, changing, or stopping any protocol.

Q: Who is Peptid AI for?
A: Adults who self-manage research peptide protocols — athletes, recovery-focused individuals, longevity self-experimenters, biohackers, and clinicians who want a clean personal log alongside their patients.

Q: Which platforms does Peptid AI support?
A: iOS (iPhone, iPad) and Android (phones, tablets). A web preview is in the works.

Q: I’m a complete beginner — where should I start?
A: Read three guides before your first injection: "Bacteriostatic Water Explained", "How to Calculate Peptide Reconstitution", and "Build Your First Peptide Protocol". They are linked from the /guides page. After that, open the in-app library, pick the peptide your clinician approved, and the protocol setup wizard walks you through dose, frequency, route, and reminders in about 90 seconds.

Q: Does Peptid AI tell me what dose to use?
A: No. Peptid AI never prescribes. The peptide library shows ranges typically reported in research literature for context. Every dose you log is one you and your physician set together. The app is the log; the protocol decision is yours.

Q: How often is the peptide library updated?
A: Library entries are reviewed quarterly and updated when new peer-reviewed evidence, approval status, or safety guidance changes. We add new peptides on demand — if you’re tracking something not in the library, email us and we’ll add it.

### Privacy and data

Q: Where is my data stored?
A: It syncs to your private, EU-hosted account (Supabase), so it is available across your devices. No manual sign-up is required to start — an anonymous account is created for you — and you can export your data anytime as TXT or JSON, or delete everything with a single tap. We never sell your data.

Q: Do you sell or share my data?
A: No. We do not sell, rent, or share your personal data. We use a minimal set of processors strictly to operate the service: our EU cloud host (Supabase) for storage and sync, Apple/Google for app distribution and payments, and — only when you use the optional AI assistant — the AI provider that powers it. See the privacy policy for the full list.

Q: Do you use Google Analytics or marketing trackers?
A: No. Peptid AI does not use Google Analytics, Firebase Analytics, Mixpanel, or any advertising SDK. No tracking pixels. No marketing cookies. The only cookie we set is the consent record for the cookie banner itself.

Q: Will my data sync between my iPhone and my Android tablet?
A: Yes. Your data syncs through your private, EU-hosted account (Supabase), so it stays in sync across iPhone, iPad, and Android. Sign in with Apple or Google to link your devices; you can also export TXT/JSON anytime.

Q: How do I delete my data?
A: Two ways: in-app under Settings → Account → Delete account, or email akremagency@gmail.com. See the delete account page for the full process and the data we retain (none, except as required by tax law for billing records).

Q: Is Peptid AI GDPR compliant?
A: Yes. We follow GDPR principles by default: minimal data, opt-in for everything optional, offline-first with EU-hosted sync, right to export, right to deletion. See the privacy policy for the full data map and our DPA template if you need one.

### Pricing and billing

Q: How much does Peptid AI cost?
A: Two subscription plans: €7.99 per week (with a 3-day free trial for new subscribers) or €79.99 per year (no trial — yearly works out to about €1.54 per week and saves roughly 81% vs paying weekly). Both are Premium: unlimited protocols and vials, and the AI Coach. Without a subscription the app stays free, with 1 active protocol at a time, up to 3 vials, no AI Coach and a daily limit on vial label scans.

Q: How does the 3-day free trial work?
A: New subscribers on the Weekly plan get 3 days of full access at no charge. The trial converts to a paid Weekly subscription (€7.99/week) unless you cancel at least 24 hours before it ends. The trial is one-time per user / Apple ID / Google account, and is only on the Weekly plan.

Q: Why no free trial on Yearly?
A: Yearly is already 81% cheaper than weekly when amortised. We don’t want to use the free-trial pattern to push longer commitments. If you’re unsure about a year, try the 3-day weekly trial first.

Q: How do I pay?
A: Subscriptions are billed through Apple (iOS) or Google Play (Android). Your local currency and any applicable VAT are shown at checkout.

Q: Can I cancel anytime?
A: Yes. Cancel in your App Store / Google Play account at any time. You keep access until the end of the billing period. To avoid being charged after the free trial, cancel at least 24 hours before it ends.

Q: Do you offer refunds?
A: Refunds are handled by the platform you purchased on (Apple or Google) per their policies. We will assist if a refund is mistakenly denied — email us with your order ID.

Q: Is there a student or healthcare-worker discount?
A: Not currently. The yearly plan at ~€1.54/week is our best rate for everyone.

Q: Can I get a tax-deductible invoice for the yearly plan?
A: Yes. For App Store / Google Play purchases, the platform issues the invoice — email us if you need help retrieving it.
