The future of peptide research.
A peptide research library for iOS. Browse 122 compounds from published literature, ask the AI, and keep your own data organized. Research only — not medical advice, and never a prescription.

Home, Insights, Log, AI, Stack
Nine tools. One research focus.
Every feature in Peplab ai serves one goal — help you read the research, organize what you find, and watch your own data move. Nothing prescribes. Nothing persuades you to buy anything.
122 peptides. Always framed as what research describes.
Filter by category, FDA status, mechanism, or research area. Every entry links back to the PubMed papers it came from.
AI chat over the library
A streaming AI chat powered by a RAG index of the peptide catalog. Every answer cites the entries it draws from. Research and education only.
Stack builder
Assemble a personal reference list from the library. Add your own notes and observations alongside what the literature describes.
Bloodwork log
Log lab panels by date and watch markers trend over time. Export to CSV to share with your clinician.
HealthKit integration
Pull heart rate, HRV, sleep, steps, weight, and more. Your data stays on device unless you choose to sync.
Vial math utility
A simple calculator for vial concentration arithmetic. Useful for anyone working with research-grade compounds in a lab context.
Body scan
Take periodic photos and keep a visual log. Review changes week over week alongside your other data.
A research library that fits in your pocket.
Every peptide in Peplab ai is sourced from published literature. We do not write protocols for you. We show you what research describes, and we let you organize it.
Semaglutide
GLP-1 agonist. FDA-approved for type 2 diabetes and weight management.
Tirzepatide
GIP/GLP-1 agonist. The most effective approved weight-loss drug to date.
BPC-157
Synthetic peptide fragment. Research-backed for tissue repair.
CJC-1295
GHRH analog. Often paired with Ipamorelin for synergistic effect.
Retatrutide
Investigational triple agonist. Phase 2 data showed 24% reduction at 48 weeks.
Ipamorelin
Selective GH secretagogue. Widely considered the cleanest in its class.
Testosterone
Injection protocols with cycle-aware logging and bloodwork tracking.
Real citations. Not opinions.
Every peptide entry links back to the source material it came from. When you read about a mechanism, you can click through to the paper behind it. When the AI answers, it cites the entries it drew from. Peplab ai does not invent data, rank compounds by effectiveness, or publish dose recommendations.
Ask the library anything.
Peplab ai streams answers from a retrieval index built on the peptide catalog. Every response is grounded in the entries it cites. It never tells you what to take.
- →Retrieval-augmented — only answers from the library it was given.
- →Every answer cites the entries it drew from.
- →Refuses medical advice and self-administration guidance by design.
- →Streams responses. Reads like a careful lab partner, not a hype account.
Built for people who read the papers.
Peplab ai is designed for clinicians, researchers, and disciplined self-experimenters. Early users call it the first peptide app that respects their time.
"I have spent years digging through PubMed tabs. Peplab ai is the first tool that puts the library, the citations, and my own biomarker data in one calm place."
Functional medicine researcher
"The vial math utility alone saves me time every week. The chat is the bonus. It reads like a careful lab partner, not a hype account."
Independent biohacker
"Dark, fast, quiet. No ads, no supplement pop-ups. Finally a peptide app that is not trying to sell me something on every screen."

Built by someone who needed it.
I was the guy with a Google Sheet, a pharmacy receipt folder, and no idea if it was working.
"I was running four compounds off a crumpled notebook, and I knew I wasn't alone."
We built the tracker we wanted: obsessive about the data, respectful of your time, honest about what the research does and doesn't say. No hype. No shady sourcing. Just a quiet, well-designed log that makes your next appointment easier.

Common questions.
Everything you'd want to know before tracking your first dose.
Is this medical advice?
No. Nothing in Peplab ai is medical advice, a diagnosis, a treatment plan, or a prescription. Everything the app presents is framed as what published research describes. The peptides catalogued are research compounds, most of which are not FDA approved for human use. Always consult a qualified clinician.
Does the app recommend doses or help me buy peptides?
No and no. The app does not recommend doses or tell you what to take. When dosing information appears, it is labelled as what researchers described in published studies. The app does not sell peptides and does not help you acquire them. It is a research and organization tool, nothing more.
How does the AI chat work?
The chat uses retrieval-augmented generation on a private index of the peptide library. When you ask a question, it pulls relevant entries, passes them to the model, and streams back an answer with citations. It is scoped to research framing and refuses medical advice and self-administration guidance.
Is my data private?
Yes. Your data is encrypted in transit and at rest. We don't sell personal or health data to advertisers, and HealthKit data is only synced to our servers if you explicitly opt in. See our Privacy Policy.
Which peptides and compounds are supported?
120+ out of the box, covering GLP-1s, peptides, TRT, growth hormone secretagogues, and recovery compounds. You can also add custom compounds.
Do you integrate with Apple Health?
Yes. Weight, steps, sleep, and heart rate sync automatically once authorized. Only the categories you approve are read.
What happens to my data if I cancel?
Your logs and exports stay available in read-only mode. You can export or permanently delete everything from Settings at any time.
Is there a free trial?
Yes — a 3-day free trial on the weekly plan. Full access, cancel anytime in App Store settings.
Your next log is the easiest one you'll take.
iOS first. Android in the queue. 3-day free trial — no card required to browse.
Peplab ai is a tracking and education tool — not medical advice. We don't prescribe, sell, source, or recommend any compound. Many peptides discussed are not FDA-approved for general human use and some may be illegal in your jurisdiction. Always consult a licensed clinician before starting, stopping, or changing any protocol. Peplab is not a substitute for a doctor and is not intended to diagnose, treat, cure, or prevent any disease.
