About Tirzepatide

Tirzepatide is a dual GIP and GLP-1 receptor agonist studied for glucose regulation in type 2 diabetes and for effects on appetite and body weight. Its long half-life supports commonly reported once-weekly use. This entry is informational and is not a recommendation to use the compound.

More on this compound — including its half-life curve — on the Tirzepatide compound page and the Tirzepatide half-life chart.

Questions, answered.

What inputs do I need for a Tirzepatide reconstitution calculation?
Use the strength printed on your own vial, the exact diluent volume you actually added, and the target amount supplied by your qualified healthcare professional. Peptilot does not choose a dose or diluent volume; it only converts the three numbers you enter.
How does the calculator convert Tirzepatide mg to U-100 syringe units?
It first divides vial strength by diluent volume to calculate mg/mL. It then divides the target amount by that concentration to get mL, and multiplies mL by 100 for a U-100 syringe. This is dimensional arithmetic, not a mixing or dosing recommendation.
What vial sizes does Tirzepatide commonly come in?
The Peptilot catalog includes 5 mg, 10 mg, 15 mg as commonly encountered package strengths. This is a convenience list, not a validation of any product or vendor. Always use the strength printed on your own verified label.
Can Peptilot remember my vial and do this automatically?
Yes — the Peptilot web app stores each vial's strength and diluent, shows the draw for any dose instantly, tracks remaining volume as you log doses, and reminds you when a dose is due. It runs in any browser and starts with a 3-day free trial. This calculator stays free and needs no account.

Educational information for people who track their protocols — not medical advice, and never a recommendation to use any compound. Always work with a qualified healthcare provider.
