PeptideWiz vs Regimen
Both are strong iOS peptide trackers with a free tier and a low-cost subscription. They lean in different directions: Regimen toward pharmacokinetic modeling and data correlation, PeptideWiz toward protocol logistics — inventory, refills, reminders, provider reports, and a full suite of free calculators. Here’s an honest side-by-side.

Where each one wins
Choose PeptideWiz if…
- + You want tight inventory, refill, and expiration tracking so you never run out mid-protocol.
- + You value a doctor-ready PDF report to bring to appointments.
- + You use the free web calculators (general + per-compound) and want the same math in the app.
- + You want privacy-level controls on what notifications reveal, plus email/push summaries.
- + You prefer a tool with a conservative, non-medical-advice posture.
Choose Regimen if…
- • You want pharmacokinetic curves that model concentration between doses.
- • You want to correlate symptoms and bloodwork against your dose timeline.
- • You need an Android app.
Regimen is a genuinely good app — if PK modeling or Android is a must-have, it’s the better fit.
The honest summary
If your priority is data modeling — pharmacokinetics, correlations, Android — Regimen leads. If your priority is running a protocol day to day — knowing exactly how much to draw, never running out of a vial, getting a clean report for your provider, and keeping notifications private — PeptideWiz is built around that, at the same price. Many people start with the free calculators and the free tier of either app before subscribing.
