Peptide injection tracker
Tirzing tracks any injection you add, each with its own name, unit, schedule, half-life and vial or mix. This page covers the ones without a guide of their own.
Free plan with no time limit and no card. Works in any browser, with an Android app.
What people log
Members use Tirzing to log things like vitamin B12, NAD+, MIC and lipo blends, cagrilintide, BPC-157, TB-500, ipamorelin, CJC-1295, tesamorelin, sermorelin and GHK-Cu.
Some of these are approved medicines and many are not. Tirzing doesn’t check, sell, recommend or endorse any of them, and nothing on this page is dosing or medical advice.
How Tirzing handles any injection
Each medication you add is set up on its own terms, from the details you enter.
-
Any name, any unit
Add a medication with the name on your label and the unit you measure in: mg, mcg, mL or another unit.
-
Its own half-life
Pick from the quick-start list where it applies, or enter a half-life yourself. You can change it at any time.
-
Vials, blends and mixes
A vial of one ingredient, a blend of several, or a mix you take by the mL, which counts down in mL.
-
Several on different schedules
Each medication has its own schedule and its own shot reminder.
-
One log for everything
Every shot, whatever it was, with its time and injection site, in one history.
-
An estimate from your own log Paid plans
A level curve for each medication, built from the shots you logged and the half-life you entered.
-

What it looks like in the app
A sketch of three things you see after logging, with made-up entries.
Adding an injection that is not on the list
- Open Medications and choose Add medication.
- Type the name from your label, set the dose unit, and enter a half-life if you have one.
- Enter its schedule as it was set for you.
- Add the vial, blend or mix under My supply, then log each shot against it.
Questions about tracking it
Can I track an injection that is not on the list?
Yes. Add it by name, choose its unit, and enter a half-life if you have one. It works like any other medication in Tirzing.
Can I log doses in mcg?
Yes. A medication set to mcg is logged and counted down in mcg, and its vial strength can be entered in mcg per mL or mg per mL, whichever the label uses.
Can I track a mix I take by the mL?
Yes. Add it as a vial of one medicine with the mix’s name, and log each shot as the mL you draw. The vial counts down in mL.
Can I track several on different schedules?
Yes. Each medication has its own schedule, supply and reminder.
Does Tirzing recommend or sell any of these?
No. Tirzing is a tracking app. It doesn’t sell, recommend or endorse any substance and gives no dosing or medical advice.
