## What is PepStak?

PepStak is the all-in-one peptide tracker: plan your stacks, calculate exact doses, log every injection, and see your active levels in real time.

SEE REAL-TIME PEPTIDE LEVELS
Know what's actually in your system. PepStak models each peptide's active level from your logged doses and half-life, so you always know where you stand.

CALCULATE EXACT DOSES
The reconstitution calculator turns vial size, bacteriostatic water, and target dose into exact syringe units — no more napkin math before every injection.

STACK MULTIPLE PEPTIDES
Build goal-based stacks that group your peptides, schedules, and progress in one place. Track duration, weight intent, and completion as you go.

LOG SMARTER INJECTIONS
The interactive body map shows your recent injection sites with rotation guidance and best-site suggestions, so you never overuse a spot.

STAY CONSISTENT
Dose reminders keep you on schedule. Daily check-ins track energy, mood, sleep, appetite, and side effects so you can see how your protocol is really going.

TRACK YOUR PROGRESS
Progress photos and weight tracking put your results side by side with your protocol history.

COMPREHENSIVE PEPTIDE LIBRARY
Browse 100+ peptides with detailed profiles, or create custom peptides to match exactly what you're running.

SYNC & BACKUP
Secure cloud sync keeps your data safe and available across devices.
