Features

Everything you need to dose with confidence

SubQ replaces spreadsheets, guesswork, and forum posts with real tools backed by pharmacokinetic data.

Interactive Dose Calculator

Visual syringe reconstitution tool. Enter your vial size, water volume, and target dose. See exactly how many units to draw.

Blood Level Charts

Real-time pharmacokinetic tracking shows estimated blood concentration over time, based on published half-life data.

Smart Protocol Templates

Community-vetted dosing schedules for common peptides. Start from a template, then customize timing and amounts.

Injection Site Rotation

Visual body map tracks every injection site. Never hit the same spot twice. Reduces scar tissue and improves absorption.

Doctor Export

Generate clean PDF and CSV reports of your dose history. Share with your provider at your next appointment.

Apple Health Sync

Keep all your health data in one place. SubQ syncs with Apple Health so your peptide data lives alongside everything else.

How it works

Up and running in three steps

No onboarding maze. No account required. Just open the app and start tracking.

1

Pick your peptide

Choose from the built-in database or add a custom compound. We include half-life data, reconstitution info, and common dose ranges.

2

Set your protocol

Use a community template or build your own schedule. Set dose amounts, frequency, and injection sites.

3

Track and optimize

Log each dose with one tap. Watch your blood level charts update in real time. Adjust your protocol based on actual data.

What people are saying

Trusted by the peptide community

Real feedback from people tracking their protocols with SubQ.

★★★★★

"I was managing BPC-157 and Semaglutide on a spreadsheet. SubQ replaced all of it in five minutes. The blood level charts alone are worth the subscription."

"Finally something that doesn't look like it was built in 2008. The injection site rotation map is brilliant. My nurse practitioner loved the PDF export too."

"The reconstitution calculator is the one feature I use every single time. No more second-guessing the math at 6am. Simple, fast, and accurate."

FAQ

Common questions

Quick answers about SubQ, your data, and how it all works.

SubQ ships with a database of commonly used peptides including BPC-157, Semaglutide, Tirzepatide, CJC-1295, Ipamorelin, TB-500, and many more. You can also add any custom compound with your own half-life data and dosing parameters.
Yes. All your data is stored locally on your device. We don't have servers collecting your health information. If you use Apple Health sync, that data stays within Apple's encrypted Health ecosystem. We never sell or share your data with third parties.
The charts use published pharmacokinetic half-life data to model estimated blood concentration curves. They're based on standard single-compartment models. These are estimates, not lab results. Pro users can adjust half-life values to fine-tune the model to their individual response.
Absolutely. SubQ Pro is billed through the App Store. You can cancel anytime in your Apple ID subscription settings. You'll keep Pro access through the end of your billing period. No hoops, no retention screens.
No. SubQ is a tracking and calculation tool. It does not prescribe, recommend, or diagnose anything. Always work with a qualified healthcare provider for medical decisions about peptide therapy. The app was designed by a physician to help patients and providers communicate more effectively.
Free gives you the dose calculator, peptide database, 2 active protocols, a 7-day dose log, and blood level charts. Pro unlocks unlimited protocols, full dose history, peptide stacking, injection site rotation map, progress photos, Apple Health sync, doctor exports, the half-life editor, and advanced cycle support.
Yes. Since all data is stored on your device, SubQ works without an internet connection. You can log doses, run calculations, and view your charts anytime, anywhere.
SubQ was designed and built by an emergency medicine physician who saw patients struggling to track peptide protocols with spreadsheets and notes apps. The goal was to build something that's actually useful for both patients and their providers.
