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.
PepOS pays for itself.
Bad reconstitution math, expired vials, and inefficient dosing protocols cost you money. See how much you could save.
Industry average without precise tracking is ~10-15% due to reconstitution rounding, over-drawing, and expiration.
