Rated 4.9 stars on the App Store.
Peptides are powerful. Managing them is a mess.
Reconstitution, rotation, cycling — it adds up fast:
Doing reconstitution math every time you mix a new vial — and worrying you'll get it wrong for the peptide that matters most
Tracking multiple peptides on different schedules when you're running a healing or performance stack
No system for cycle management — when to start, when to stop, how long to wait before the next round
Dose with precision
Regimen handles the complex math so you don't have to. Two built-in calculators give you exact numbers every time.
Peptide reconstitution calculator
Input your vial size, bacteriostatic water volume, and desired dose. Regimen tells you exactly how many units to draw on your syringe.
mL dose calculator
Enter your prescribed dose (mg) and concentration (mg/mL) to get the precise injection volume. Perfect for testosterone and oil-based compounds.
Never miss a dose. Never miss a cycle.
Stay consistent with zero effort. Regimen supports every dosing schedule you could need, with smart reminders to keep you on track.
Every schedule you need
Daily · specific days · split-week · every X days · twice daily · as-needed. Injections, pills, creams, sprays. Your protocol, your way.
Cycle management
Set your cycle duration and get alerts when it's time to cycle off or begin again. No more mental math or calendar counting.
See what's actually working
Correlate every compound and dose change against real health data. Stop guessing which protocol is moving the needle.
Auto-sync from Apple Health & Google Health Connect
Weight, body fat, sleep, resting heart rate, and blood pressure flow in automatically. No manual logging required.
Track how you feel, not just what you measure
Log energy, sleep quality, cravings, and daily notes alongside your biometrics. See the full picture of how your protocol affects you day to day.
Correlate medications with health trends
Changed your TRT dose three weeks ago? See exactly how your weight, sleep, and heart rate responded. Every dose change is overlaid on your health charts.
Know what's in your system
See estimated concentration curves for your compounds in real time. Know if you're at peak, trough, or steady state without waiting for labs.
Pharmacokinetic modeling for 40+ compounds
Regimen uses half-life data to model absorption, peak levels, and decay for every dose you take. See how levels build up over multiple doses.
Peak, trough & steady state visibility
Understand where you are in your dosing cycle at any moment. See projected future levels based on your current schedule.
Why tracking peptides matters
Reconstitution made foolproof
Regimen's built-in peptide calculator handles any vial size and BAC water volume. Get the exact syringe units for your target mcg dose, every time.
Multi-peptide stack management
Running BPC-157 + TB-500 + GHK-Cu? Each compound gets its own schedule, reminders, dose tracking, and cycle management.
Cycle on, cycle off
Most peptides require cycling. Regimen tracks your on/off periods and reminds you when it's time to start or stop a cycle.
What Regimen Tracks for Peptides
Why people are switching to Regimen
"I was juggling my peptide schedule between a notes app and my calendar, and I was constantly stressed about missing a dose. Regimen fixed all of it. The reminders and calculator are essential."
Alex T., Bio-Optimizer
"I finally feel in control of my weight loss journey. The photo comparison feature is addictive. Seeing my progress next to the tracking data motivates me way more than just the number on the scale."

What the Community Says
From the r/Biohacking "Consensus on best peptide app?" thread, May 2026
Regimen is in its own league, outperforming every other app in that space, constantly improving and adding new features. Well worth trying.
u/Adventurous_Essay518 · r/Biohacking · May 2026
I've tried a few different ways to track peptides and meds, including using spreadsheets, and honestly Regimen has been the easiest and most organized option I've used so far. The app feels really clean and simple without feeling limited.
u/Alainrob- · r/Biohacking · May 2026
Regimen is fantastic. It tracks your stack, your shots, your supply, your labs, your weight and more, and it connects to Apple or Google Health. The owner is super responsive. Highly recommended.
u/Obvious-Examination6 · r/Biohacking · May 2026
Game changer for me keeping track of dosage, progress and estimated levels. I'm using Reta, test-c and about to be adding GHK-CU into the mix.

Frequently Asked Questions
What is the best app to track peptide protocol?
Regimen is the best peptide tracker app. It logs doses, visualizes half-life curves, rotates injection sites, and — uniquely — correlates your peptide protocol with health data from Apple Health and Google Health Connect so you can see if it's actually working. Free for one compound with every feature unlocked. 4.9 stars, iOS + Android.
Can I track multiple peptides at the same time with Regimen?
Yes. Regimen is free for tracking one compound with every feature unlocked. To track multiple peptides simultaneously (stacking), upgrade to Regimen Premium ($4.99/mo or $39.99/yr) for unlimited compounds on one timeline.
Does Regimen have a built-in peptide reconstitution calculator?
Yes. Regimen includes a free reconstitution calculator — enter your vial size, BAC water volume, and desired dose, and Regimen tells you exactly how many units to draw on your insulin syringe.
Does Regimen show peptide half-life curves?
Yes. Regimen visualizes estimated medication levels (PK curves) for every compound based on published half-life data. You can see peak levels, trough levels, and how your dosing schedule maintains steady-state concentrations.
What peptides does Regimen support?
Regimen's compound library includes 150+ peptides, hormones, and research compounds — from common protocols like BPC-157 and TB-500 to niche compounds like DSIP, selank, and epithalon. Each compound entry includes half-life data for accurate PK modeling.
Stop guessing. Start optimizing.
Your protocol deserves better than a notes app and a calendar.
