Peptalog
Peptide Protocol Tracker
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Track every entry, manage vials, follow your protocol, and convert units in seconds. Private, offline-first, and built for serious peptide users.
Peptalog is the personal tracking and research journal built for peptide users who want every part of their protocol organized in one private, offline-first app.
• LOG ENTRIES
Record every entry with timestamp, site rotation, and notes. Build a complete history with one tap.
• MANAGE VIALS
Keep a private inventory of every vial — lot number, reconstitution date, storage temperature, expiration warnings, and remaining amount. Scan barcodes, attach photos, and never lose track of what's left.
• FOLLOW PROTOCOLS
Build cycling schedules with tiered ramp-ups, taper-downs, and rest weeks. Get reminders for upcoming entries and clear status when something gets skipped.
• SOLUTION CALCULATOR
A research and educational unit-conversion tool. Convert between vial mg, BAC water mL, and syringe units to figure out reconstitution and concentration. Not a medical device — for research and educational purposes only.
• RESEARCH LIBRARY
Browse a curated database of peptides with mechanism summaries, half-lives, common stack patterns, and links to source studies.
• BLOODWORK TRACKING
Log blood marker results over time and view them on charts so you can correlate changes with your protocol.
• LEVEL CHART
Visualize estimated peptide concentration across the last 24 hours from your tracked entries and known half-lives — purely informational, helpful for timing.
PRIVATE BY DESIGN
• Encrypted local storage on your device
• Optional end-to-end encrypted cloud sync
• Biometric lock (Face ID / Touch ID)
• Export your data anytime as JSON
• Delete your account and all data with one tap
