Log a shot in seconds, follow the plan you set, and walk into your next appointment with a clean report. Stax keeps it all on your phone.


Pick the peptide, the amount and the unit. Stax remembers your usual names and units, so most logs take a few seconds.

Enter the days, amounts, step-ups, phases and off-cycles you follow. Stax shows what's left today and what each vial has left.

Your month at a glance, a day streak, a calendar of every shot, and a trophy shelf that's surprisingly motivating.

One tap makes a clean PDF of your plan and what you actually logged, day by day. Send it before your appointment or show it on your phone.

Your patients log every shot against the protocol you set and bring a clean, day-by-day report to each follow-up. Stax records. It never recommends.
Create your clinic account in the portal, or apply below. Stax passes go on sale soon.
Why clinics use Stax
Every logged shot with peptide, amount, unit, time and site. No more "I think I took it most days."
Today's shots on the home screen, discreet reminders, streaks and trophies keep patients coming back to it.
The protocol lives in the app, with step-ups, phases and off-cycles, so patients can check it themselves.

Stax saves only what you enter into it, and it saves it on your device:
None of this is sent to us or to anyone else.
When you make a doctor report, Stax creates a PDF on your phone. It goes only where you choose to send it, using your phone's own share sheet. We never receive a copy.
If you allow notifications, reminders are scheduled by your phone itself. They are not sent from a server, so no one receives a record of them. The reminder text never names a peptide and never mentions injections or doses.
You can turn reminders off in the Plan tab or in your iPhone's Settings at any time.
If you back up your iPhone with iCloud or a computer, Apple may include Stax's saved data in that backup. Those backups belong to your Apple account and are covered by Apple's privacy policy. We have no access to them.
We do not sell, rent or share your information. We could not if we wanted to, because it never leaves your phone.
Because we hold none of your data, there is nothing for us to look up, export or delete on your behalf.
If a clinic sends us an application through this site, we receive the details entered in the form and use them only to review the application and reply.
Stax is intended for adults. It is not directed at anyone under 18.
Stax is a personal tracking tool. It does not recommend, diagnose or treat anything, and nothing in it is medical advice.
If Stax ever changes what it stores or starts sending anything off your phone, this page will be updated first, with a new effective date at the top.
Questions about this policy: hello@staxtrack.com
This policy applies to the Stax: Peptide Tracker app for iPhone and to staxtrack.com.
Thanks. We review every clinic within one business day and reply by email.
