Your journey, gathered in one private Lab.
A dose in one note, a vial date in another, health readings somewhere else. The Peptarch’s Lab brings those records together, with a place for how you feel and what you measure.
Full access includes Today, Trends, Vault, and Journal in the private Lab.
See your day at a glance.
Keep product names, recorded amounts, routes, and subcutaneous sites together. A body map helps you see where you logged a site. Convert only the amounts and concentrations you enter.
Your records, without suggested doses.
Health observations, with your permission.
Connect Apple Health to read weight, resting heart rate, sleep, and steps. Glucose and blood pressure are separate opt-ins. Readings refresh when you open or return to the Lab, with their dates and sources. The Lab also works with manual entries and without Health access.
A small reminder to check in.
Choose a daily check-in reminder or a vial-date reminder. Notifications stay generic and private. Dates come from your label or pharmacy instructions; a reminder does not establish a vial’s safety or shelf life.
New Lab records stay encrypted on your iPhone, excluded from backups and never sent to our servers or AI. You control Apple Health access and can erase your local records in Lab settings. Deleting the app or losing your iPhone can remove these records.
How Lab privacy worksA guided welcome in V1.5
Meet your guide. Find your way.
Scroll through Evidence, Peptarch, Learn, and Lab before personalizing your library. Larger Peptarch reflections and animated previews help explain what each part is for.
Learn with Peptarch
Understand every answer.
Play five-question rounds, read sourced explanations, earn stars, and return to questions you missed. Anatomy and measurement guides stay close at hand.
Learn at your own pace.
Actual V1.5 screens with example records. English screens shown; the app also supports French.
Your research interests still shape the library. The Peptarch helps you explore sources and learning tools; private Lab records stay outside his conversations.

Inside Peptidia
Research that reads like a reference, not a feed.
Four deliberate moves take you from a name to the source trail behind it. The interface stays quiet so the evidence can do the talking.
01Discover
Find a compound. See the evidence posture first.
Search by name or research interest, then scan evidence and risk labels before opening a profile.
✓80 review-dated, source-cited peptide profiles
02Understand
Open the Evidence Passport before the claims.
See research maturity, source strength, linked-source coverage, latest source year, and the last editorial-review date before reading mechanism or goal relevance.
✓A source score describes evidence strength—not efficacy
03Compare
Put the research context side by side.
Compare class, evidence, safety context, and citations without turning the information into a recommendation.
✓Designed for understanding, never prescribing
04Ask
Ask the Peptarch. Get a grounded answer.
The AI guide answers from the curated library and separates library entries from the specific study records supplied to each answer.
✓Inspectable answer-level study cards

Clear by design
Good questions deserve direct answers.
Peptidia is precise about what it is, what it costs, and where its responsibility ends.
No. Peptidia is an educational reference. It does not diagnose or treat any condition, generate protocols, or recommend that anyone take a compound. It is not a substitute for a licensed healthcare provider.
