Have you heard about tirzepatide, the newest injection in the market for weight loss? If you want to learn more about its dosing for weight loss, read on.
Tirzepatide Dosing for Weight Loss in Units
Tirzepatide, sold under the brand names Mounjaro and Zepbound, is gaining attention as a promising medication for weight loss. It’s approved to help manage obesity and works by activating two hormones, GIP and GLP-1, that regulate appetite and insulin. Tirzepatide mimics the two hormones, which helps with weight loss.
How Tirzepatide Helps with Weight Loss
- Reduced hunger
- It retains food in the stomach longer, making you feel satiated by smaller portions.
- Minimizes cravings for carbs and sugar.
- Lower blood glucose by helping the body burn glucose.
For anyone considering tirzepatide, understanding the dosing measured in units (milligrams) is key to getting the best results safely.
Approved Dosage Schedule of Tirzepatide for Weight Loss
Tirzepatide comes in injectable form and is given once a week under the skin. The dosing is measured in milligrams (mg). Typically, the treatment starts at a low dose to help your body adjust, then gradually increases over several weeks. This slow increase is important to keep side effects manageable and improve tolerance.
The standard dosing schedule starts at 2.5 mg weekly and can go up in steps to a maximum maintenance dose of 15 mg once per week. All injections use subcutaneous delivery, meaning the shot goes just under your skin.
Tirzepatide Compound Dosage Units
Usually, compounded tirzepatide dosage is in units administered weekly, rather than mL or mg per week, even though the concentration is in mg/mL. If you have a tirzepatide multi-dose vial, an insulin syringe may come in handy. Usually, the syringe is labeled in units. If not careful, this can be confusing.
It is important to note:
- 1 mg doesn’t always amount to one unit
- The strength of your tirzepatide will control the number of units you draw.
Example: If the vial is labeled as 10mg/mL and your prescription is 2.5 mg:
- Required dose: 2.5 mg
- Strength: 10 mg/mL
- Amount on Syringe: 2.5 mg divide by 10 mg/mL = 0.25 mL
If you will be using an insulin syringe, where the 100 line is equivalent to 1 mL, then 0.25 mL will be equal to 25 units.
If you get confused:
- Double check the tirzepatide doses in units given by the compounding pharmacy that mixed the batch you are using.
- Consult with your doctor if unsure.
Below is a sample table for 10 mg/mL.
| Dosage in milligrams | Dosage in milliliters | Units on Syringe |
| 2.5 | 0.25 | 25 |
| 5.0 | 0.5 | 50 |
| 7.5 | 0.75 | 75 |
| 10 | 1.0 | 100 |
| 12.5 | 1.25 | 125 |
| 15 | 1.5 | 150 |
Note that if you have a vial with a different strength, such as 5mg/mL, the unit will change. Always asks your doctor for specific dosing instructions.
How Many Units Is 7.5 Mg of Tirzepatide
The number of units depends on the concentration. For a 10mg/mL concentrate, 7.5 mg will amount to 75 units. This is if you are using an ordinary insulin hypodermic.
How Many Units Is 2.5 Mg of Tirzepatide
For a 10mg/mL tirzepatide, 2.5 mg equals 25 units. Once you get the higher dose levels (weeks 13-21) the concentration of the vial may change to 20 mg/mL.
Tirzepatide Dosage chart
During the first 4 weeks, your provider will administer 2.5 mg per week. After this, the dose will be increased with 2.5 mg increments every 4 weeks. Over about 20 weeks, your dose might move like this:
| Week | Dose |
| Weeks 1-4 | 2.5 mg |
| Weeks 5-8 | 5 mg |
| Weeks 9-12 | 7.5 mg |
| Weeks 13-16 | 10 mg |
| Weeks 17-20 | 12.5 mg |
| Weeks 21→ | 15 mg |
The exact final dose depends on your response and how well you tolerate the medication.
