Calculating the total milligrams (mg) in a vial

To calculate the total mg amount in each vial you must multiply the vial volume by the concentration dose per 1 milliliter.

In the picture above, the concentration is 5mg/0.5mL, meaning there are 5mg of medication in each half milliliter of medication. Therefore, each 1 milliliter contains a 10mg dose of medication (10mg/mL) The vial pictured above has a total volume of 2mL
2mL x 10mg/mL = 20mg vial

Example 1 (Tirzepatide starter)

The vial label may read a concentration of 5mg/0.5mL (meaning there are 5mg of medication in each half milliliter of medication)
If you received 1 vial of medication which contains 1mL and 2 vials of medication that contain 2mL, you have a total of 50mg of medication

To break that down,
1 vial with 1 mL
Each half mL contains 5mg, so every 1mL contains 10mg
1mL x 10mg = 10mg

PLUS

2 vials with 2 mL
Each half mL contains 5mg, so every 1mL contains 10mg
2 vials x 2mL x 10mg = 40mg

10mg + 40mg = 50mg total

Example 2 (Tirzepatide w/ B12 5mg weekly – 2 month supply)

The vial label may read a concentration of 10mg/mL (meaning there are 10mg of medication in each milliliter of medication)
If you received 2 vials of medication which each contain 2 mL, you have a total of 40mg of medication

To break that down,
2 vials with 2 mL each = 4 mL total
Each mL contains 10mg

4mL x 10mg = 40mg total

Example 3 Semaglutide Starter

The vial label may read a concentration of 2.5mg/mL (meaning there are 2.5mg of medication in each milliliter of medication).
If you received 2 vial of medication which each contain 1mL, you have a total of 5mg of medication 

To break that down,
2 vials with 1 mL each = 2mL total
Each mL contains 2.5mg

2mL x 2.5mg = 5 mg total
