Log doses, watch concentrations decay in real time, and stay on protocol. Your data stays on your device — no accounts, no tracking, no cloud.
Built by someone who actually tracks peptides. No gimmicks, no "AI-powered" marketing — just real data, local storage, and charts that update with every log.
Real-time plasma-concentration curves across every active peptide. See timing overlap, peak windows, and when to dose next — recomputed on every log.
ProContext-aware cards on your stack — timing, missed-dose impact, cycle wrap-up. Driven by your logs, not generic advice.
ProCurated cycles for healing, growth, longevity, recovery, and metabolic goals. Tap to start — schedule and doses configured.
Built in. Vial totals, BAC water, concentration, remaining mg. Math auto-derives from any two inputs. Never guess on syringe units again.
Adherence by peptide, streaks, missed-dose patterns, and a calendar that distinguishes rest days from missed days. All on-device.
Every dose log and protocol is stored locally on your device in an encrypted SQLite database. No account. No analytics. No third-party tracking. Ever.
No onboarding gauntlets, no dashboards you'll never look at. Every screen earns its place.
Every dose you log updates the curve instantly. See plasma concentration across all active peptides on one chart — peak windows, timing overlap, when to re-dose.
Half-Life Stack · Pro
The Peptide Guide reads your active peptides and flags which ones stack well, which share contraindications, and where timing might conflict. Based on your real logs — not a generic LLM chat.
Peptide Guide · Pro
Start one of 28 curated templates or build your own cycle. The app tracks week progress, schedules dose reminders, and surfaces a clean countdown so you always know what's next.
Protocols · Free templates included
Tap to log, pick site from a body diagram, done — under 5 seconds per dose. The body map shows recent injection sites colored by age so you can rotate intelligently.
Quick Log + Site Map · Free
Every dose log and protocol lives on your device in an encrypted SQLite store. No account creation, no cloud sync, no analytics SDK. Delete the app and the data is gone.
