Semaglutide & Tirzepatide Calculator
Pick the compound, enter your vial's mg and the water you added, and we calculate the units to draw for each phase of the weekly titration.

How titration works
- 1Semaglutide and tirzepatide are increased gradually (titration) to reduce side effects.
- 2Enter your vial's mg and the bacteriostatic water you added: that sets the concentration.
- 3The table shows, for each weekly phase, how many units to draw on the U100 syringe.
- 4Tap a row to see that phase drawn on the syringe.
Frequently asked questions
What's the typical semaglutide titration?
The reference schedule starts at 0.25 mg weekly for 4 weeks, then 0.5 mg, 1.0 mg, 1.7 mg, and up to 2.4 mg maintenance, changing every 4 weeks. Your doctor may adjust it to your case.
And tirzepatide?
The reference schedule starts at 2.5 mg weekly and increases every 4 weeks: 5, 7.5, 10, 12.5, and up to 15 mg maintenance. Always as medically directed.
Why does it give units, not mg?
Because in the syringe you draw volume, not weight. The calculator converts each phase's mg into the exact U100 syringe units based on your vial's concentration.
Does this replace my doctor?
No. It's an informational calculation tool. Semaglutide and tirzepatide are prescription medicines: their use and dosing must be directed and supervised by a healthcare professional.
This tool is for informational and educational purposes only. It is not medical advice and does not replace a healthcare professional. Peptides and GLP-1 medications should be used under medical supervision. Testosterone replacement therapy (TRT) is a prescription hormonal treatment: it should only be started after lab-confirmed deficiency and with ongoing medical follow-up, never on your own. Always consult your doctor before starting or adjusting any protocol.
