Most peptide apps are reminders with a calculator stapled on.
You're running a stack — BPC, CJC, Ipamorelin, Reta, maybe TRT alongside it — at $300–400 a month. And the best tool for managing it is a Notes app you forgot to update, a spreadsheet that lost your reconstitution dates, or a peptide tracker one user called "primitive" in the age of AI.
COMPOUND is the protocol intelligence layer for serious operators. Built on actual pharmacology and peer-reviewed research. Not a timer. Not a generic medication app. The instrument your stack deserves.
AI STACK ANALYZER*
Drop in your full protocol — BPC-157, TB-500, CJC-1295, Ipamorelin, GHK-Cu, MK-677, Tesamorelin, Retatrutide, testosterone, anastrozole, hCG. The AI surfaces interaction warnings, timing conflicts, redundant pathway flags, and absorption issues. Every warning cites peer-reviewed research. Re-runs on any protocol change.
The exact problem Andrew Huberman called out: "make sure you're not redundantly hitting a pathway."
SIDE-EFFECT CORRELATION ENGINE*
Log quick daily symptoms. The AI maps every symptom against your dose timeline and surfaces patterns you couldn't find yourself. Insomnia tracking back to evening CJC dosing. Nausea aligned with a specific titration. Mood shifts that correlate with E2 troughs.
BLOODWORK OCR SCANNER*
Photograph lab results — Marek, Defy, Quest, Labcorp, anywhere. The AI extracts every marker (free T, total T, E2, IGF-1, CRP, AST/ALT, A1C, lipids, hematocrit) and maps them on your protocol timeline. See what's actually working in your bloodwork.
For every TRT operator told they're "in range" while symptoms persist: this is the receipts.
SMART RECONSTITUTION
Stepped input or natural language*. "10mg vial, I want 250mcg twice daily." Get exact syringe markings, vial duration, BUD tracking, and storage instructions. No more mental math at 6am.
42-COMPOUND DATABASE
Every entry includes half-life, mechanism of action, primary research areas, key studies with PubMed links, regulatory status, common protocols, and known interactions. Written for people who take the science seriously.
PROTOCOL AI CHAT*
Ask anything about YOUR stack. Every answer is grounded in your own protocol data, your own symptom log, your own bloodwork — not in a generic ChatGPT response that doesn't know what you're running.
INTERACTIVE STACK PHARMACOKINETICS*
See your full stack on a serum concentration curve. Drag dose timing to watch coverage shift across the day. Stack cycles calendar. Cross-cycle comparison. Smart restart assessment.

WHO COMPOUND IS FOR
- Biohackers running multi-compound peptide protocols
- TRT operators tired of being told they're "in range"
- Reta and tirzepatide users who want more than a shot tracker
- Anyone who refuses to guess with $300/month of compounds
- Researchers who already built the spreadsheet — and want it on their phone, smarter
