Peptide Calculator

Use our Peptide Calculator below to calculate accurate dosages for administering peptides using a syringe. Simply select your parameters, and our calculator will give you the results.

Draw & dose calculator

Pick your dose, the strength of your vial and how much bacteriostatic water you mixed in. We'll show you the mark to draw to on a 100‑unit syringe.

Dose of peptide

How much you want per injection.

How To Calculate

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 a visual 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.
