Reading Your Vial & Verifying Order Amounts
We frequently receive questions regarding the total amount of medication included in an order. It’s important to understand that the concentration (or strength) listed on the vial label does not represent the total number of milligrams of medication in the vial. Concentrations can vary depending on the pharmacy dispensing your prescription. Always review the label and accompanying instructions carefully with each new shipment.
Please be aware that vials may appear to be only partially filled. This is normal. Because the medication is highly potent in very small doses, only tiny volumes are required per injection—often just a fraction of a drop. For this reason, we strongly recommend documenting the amount you inject each week, as it is not possible to visually estimate the remaining volume in the vial.
Calculating the total 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
