Step 1:

Set Your Dose

Choose your intended dose in micrograms (mcg): This is the amount of peptide you plan to inject each time. This step helps th calculator determine how concentrated your solution needs to be. For instance, if you need a specific dose, the calculator can tell you how much of the mixed solution you need to use to get that dose.

Step 2:

Enter Your Peptide Strength 

Enter the peptide strength in your vial. You can select a common amount, such as 1mg, 5mg, 10mg, or 15mg. If your amount isn’t listed, you can manually type in the exact amount. This step is important because it helps the calculator know the total amount of peptide available for dilution, which is necessary for accurate dose calculation.

Step 3:

Add Your Water Volume

Decide on the volume of bacteriostatic water for mixing: Bacteriostatic water is sterile water that contains a small amount of antibacterial agent to keep the solution free from bacteria. The volume of water you add affects the concentration of the peptide solution. Enter the amount of water in milliliters (mL). For example, if you add 2mL of water, it will be recorded in the calculator. Adding more water dilutes the peptide, making each milliliter of solution contain less peptide. Conversely, adding less water makes the solution more concentrated.

Step 4:

Check the Visual Dosage Meter

Review the visual dosage meter to get your results: After entering all the information, the calculator will display avisual meter along with your results. 

You can read the peptide dose in mg, the concentration in mg/mL, and how many doses are contained in a vial. Most importantly, the results tell you how many units to draw the syringe to.

The visual meter shows you how much of the solution you need to draw up in your syringe to get the correct dose. Remember that 100 units on the syringe equals 1mL. This visual aid makes the process straightforward and reduces the chance of errors. Simply pull the syringe as far as the image indicates, and you will have the correct dosage ready to go.

Example: Calculating Your Peptide Dose

In this example we will assume your peptide strength is 5mg, and you will add 3mL of bacteriostatic water. Your goal is to inject 250 mcg of peptide into your subject.

Step 1:

Set Your Dose

Enter 250mcg which is the same as 0.25mg as your desired research dose. You want each dose to contain 250mcg of peptide, so you specify this amount.

Step 3:

Add Water Volume

You decided to dilute your peptide with 3mL of Bacteriostatic water so enter 3mL.

(Consult Bac Water Calculator to determine this amount)

Step 6:

Check the Visual Dosage Meter

The visual meter will show that you need to draw up 15 units on your syringe to get a 250 mcg dose. Since 1mL equals 100 units on the syringe, 0.15mL equals 15 units. 

Step 2:

Enter Peptide Strength

Enter 5mg in the calculator, since it says 5mg on the vial

Step 4:

What the Calculator Does

The peptide calculator works automatically when you enter the amounts above. Here is what is happening behind the scenes.

First, the calculator determines the concentration of your solution. You have 5mg of peptide, which is equal to 5000 mcg (since 5 mg = 5000 mcg). This 5000 mcg of peptide is dissolved in 3mL of water.

The calculator determines how much solution you need to draw up to get a 250 mcg dose.

Therefore, you need to draw up 0.15mL or 15 Units of the solution to get a 250 mcg dose.

Step 1:

Set Your Dose

Enter 250mcg which is the same as 0.25mg as your desired research dose. You want each dose to contain 250mcg of peptide, so you specify this amount.

Step 2:

Enter Peptide Strength

Enter 5mg in the calculator, since it says 5mg on the vial

Step 3:

Add Water Volume

You decided to dilute your peptide with 3mL of Bacteriostatic water so enter 3mL.

(Consult Bac Water Calculator to determine this amount)

Step 4:

What the Calculator Does

The peptide calculator works automatically when you enter the amounts above. Here is what is happening behind the scenes.

First, the calculator determines the concentration of your solution. You have 5mg of peptide, which is equal to 5000 mcg (since 5 mg = 5000 mcg). This 5000 mcg of peptide is dissolved in 3mL of water.

The calculator determines how much solution you need to draw up to get a 250 mcg dose.

Therefore, you need to draw up 0.15mL or 15 Units of the solution to get a 250 mcg dose.

Step 6:

Check the Visual Dosage Meter

The visual meter will show that you need to draw up 15 units on your syringe to get a 250 mcg dose. Since 1mL equals 100 units on the syringe, 0.15mL equals 15 units. 

Summary

By following these steps and using the peptide calculator, you determine that mixing 5mg of peptide with 3mL of bacteriostatic water creates a solution with a concentration of 1.7 mg/mL. To get a dose of 250mcg, you need to draw up 0.15mL (or 15 units) of this solution.
