The peptide tracker for serious protocols.
Track doses, monitor recovery, and see exactly what's working. Built for biohackers, longevity, and weight-loss protocols.
Intelligence meets physiology.
Stop guessing what works. Our AI correlates your check-ins, doses, and trends to deliver weekly deep-dive reports on your physiological response.
- Identify which compounds drive the best results
- Correlates Apple Health data (HRV, resting HR, sleep, weight)
- Predictive alerts for potential side effects
Protocol Rings
Visualize your daily adherence. Close your rings for injections, supplements, and recovery metrics to stay perfectly aligned with your goals.
Half-Life Engine
Our AI calculates precise half-lives for every compound, so you can visualize when compounds peak, overlap, and clear your system.
Stack Synergies
Our interaction checker flags compound conflicts, redundancies, and contraindications when you build protocols — with suggested safer alternatives.
The only peptide app that understands your recovery.
Automatically pull your most important biomarkers. PepOS correlates your wearable data with your peptide protocols to show you exactly what's working.
Dose Timing Optimizer.
Never guess when to pin again. Our AI analyzes your schedule, meals, and compound half-lives to recommend the absolute optimal timing for every dose.

PepOS vs. everyone else
Other apps track doses. PepOS gives you intelligence.
Trusted by protocol-serious users
"Finally, a peptide app that respects the science. The protocol intelligence is a step above any other tracker I've recommended to patients."
"I switched from a spreadsheet. Now I actually know what's working. Lost 28 lbs and the data tells me exactly which weeks moved the needle."
"The Apple Health integration is what sold me. Seeing my HRV alongside my BPC-157 cycles changed how I dose."
"Peppy (the AI) answers questions I'd otherwise spend hours Googling. Worth it just for the inventory tracking."
"My patients who use PepOS show better adherence and clearer outcome data. It's become part of my recommended toolkit."
"Clean interface, real features, no fluff. The kind of tool I wish existed two years ago."
Built for the body you're actually building.
Real users. Real protocols. Measurable change.
