Buyer's Guide · 2026
If you're running a peptide or GLP-1 protocol, the right app keeps your dosing accurate and your history in one place. Here's what to look for — and how the main options stack up.
Record dose, time, and injection site quickly — including retrospective entries.
Concentration and syringe-unit maths for the compounds you actually use.
See your streaks, your full history, and whether you're staying on protocol.
Web and mobile, so your data isn't trapped on one device.
Educational information with citations, not just marketing copy.
Your protocol data kept private, never sold, no ad tracking.
Peptidy is built specifically for peptide and GLP-1 protocols. It combines fast injection logging, free reconstitution calculators for 17 compounds, adherence tracking, body metrics, and an educational compound library with citations — across both web and iOS. If you want one tool that covers the whole protocol rather than stitching apps together, it's the most complete option.
Try Peptidy free →Consumer GLP-1 apps (such as Shotsy) are clean and easy for tracking a single weight-loss medication and weight over time. They're a good fit if you only need reminders and a weight chart, but they typically don't cover research peptides or include reconstitution calculators.
Peptidy vs Shotsy →Dedicated reconstitution calculators (such as PepCalc) handle the concentration maths well, but they don't track your injections, history, or adherence. Useful as a one-off tool rather than an ongoing tracker.
Peptidy vs PepCalc →Plenty of people start with a notes app or spreadsheet. It's free and flexible, but there are no reminders, no reconstitution maths, no adherence view, and it gets unwieldy fast once you're running more than one compound.
The best peptide trackers make logging fast (dose, time, site), include reconstitution calculators so your dosing maths is reliable, show your adherence and history clearly, and work across web and mobile. Trustworthy educational information and strong privacy matter too.
Peptidy offers a free trial, and its reconstitution calculators and educational library are free to use on the website. Notes apps and spreadsheets are free but lack reminders, calculators, and adherence tracking.
Yes — Peptidy is designed to track both research peptides (like BPC-157 and TB-500) and GLP-1 medications (like semaglutide and tirzepatide) in the same place, with calculators for each.
Reputable trackers, including Peptidy, are record-keeping tools — they don't diagnose or recommend treatment. Always consult a qualified healthcare professional before making medical decisions.
Injection logging, reconstitution calculators, and a cited compound library — free to try, on web and iOS.
