This is 150 units, past the 60-unit dial. Splitting it across administrations, or using less water to raise the concentration, brings it back into range.
Dial range varies by pen; 1–60 units is the common configuration.
Vial label
Paste into label-printer software. Nothing is sent anywhere.
The concentration is the line worth having: a vial two weeks later carries no record of how much water went into it.
Published research contexts for Tirzepatide describe 2.5–15 mg per administration. Descriptive only, not a recommendation.
Modelled level — once a week
Levels read as multiples of a single administration's peak.
- Steady-state peak
