About 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. — PepStak is a tracking and organization tool. It does not provide medical advice and does not sell or supply peptides. Always consult a licensed healthcare provider before starting any protocol. Some features require a PepStak Pro subscription.
