Everything you need to keep a clean peptide log

Set the days and times you follow and get a nudge when an entry is due. You set the schedule. Peptrack just remembers it.
Know what’s left in every vial
Track each vial from first draw to empty, with remaining supply and a low-stock heads-up before you run out.

Questions, answered
The short version: it is free, it is a record-keeping tool, and it never tells you what to take.
Is Peptrack really free?
Yes. Peptrack is 100% free to download and use on iOS and Android, and it has no ads. The calculators on this website are free too and work without an account.
What can I track with Peptrack?
Peptrack is a record-keeping app. You can log each dose with its time, site and notes, keep an inventory of your vials with the amount remaining, set reminders for the schedule you follow, and record weight, nutrition and side effects so you have accurate notes to share with your healthcare provider.
Does Peptrack tell me what dose to take?
No. Peptrack never recommends, suggests or verifies a dose, schedule or protocol. Every value in the app is entered by you. The built-in calculator only performs arithmetic on the numbers you supply. Decisions about what to take belong with you and a licensed healthcare provider.
Can I use Peptrack to track GLP-1 medications?
Yes. Peptrack works as a GLP-1 tracker: you can log each entry, record your weight over time and note side effects. Peptrack keeps the record. It does not provide medical guidance about any medication.
Do I need an account to use the free calculators?
No. The peptide calculator and the other tools on this site run entirely in your browser. There is no login and no signup, and the numbers you type are not sent to a server.
Is my data private, and can I delete it?
Your records are tied to your account and are not sold or used for advertising. You can delete your account and its data at any time from inside the app, or by following the steps on our Delete Account page.
Is Peptrack medical advice?
No. Peptrack and the tools on this site are for research, informational and record-keeping reference only. They are not medical advice and do not diagnose, treat, cure or prevent any condition. Always consult a licensed healthcare provider.
