Testosterone Dosage Calculator
Our TRT Dosage Calculator simplifies the process of calculating your testosterone replacement therapy (TRT) dosage, specifically designed for testosterone cypionate, enanthate, and propionate in commonly found concentrations. Perfect for those administering TRT using an insulin syringe.
This tool assumes the use of a 100-unit insulin syringe, equivalent to 1 mL, to provide accurate measurement for your TRT dosing needs.
How to Use the Calculator
- Input the prescribed testosterone dose in milligrams (mg).
- Select the concentration of testosterone from the drop-down menu.
- Click on the "Calculate" button to convert the dose into syringe units and mL.
- Refer to the visual representation for precise syringe measurement.
- Units matter. Concentration matters. Double check your dosage and concentration(mg/ml).
Why Use Insulin Syringes for TRT instead of big needles?
- Tiny needles.
- Easy to draw using 1/2″ 27-29 gauge sizes.
- Little to no pain.
- Less risk of developing scar tissue.
- Lower incidence of post injection site pain, swelling, and bruising.
- More practical for injecting 2-3x/wk, which most should be doing.
