TRT Dose provides educational calculators for TRT and HCG arithmetic and unit conversion. These tools do not diagnose conditions, interpret blood tests, or replace professional medical advice, evaluation, or treatment.

Example values, placeholders, and initial calculator settings are illustrations, not recommended doses or treatment schedules. Nothing on this site recommends starting, stopping, or changing a medication, dose, or injection frequency. Use your prescribed values and confirm your results with your prescriber or pharmacist.

The TRT calculator converts between mg, mg/mL, and mL using your entered dose and frequency. Every-other-day calculations use an average of 3.5 injections per week. The HCG calculator uses total vial IU, final solution volume, and a prescribed dose in IU to calculate concentration and injection volume. Neither calculator determines whether the entered values are appropriate for you.

The U-100 scale represents 100 syringe units per 1 mL, so one syringe unit equals 0.01 mL. HCG IU measure hormone activity and are not the same as U-100 syringe units. The illustration represents a 1 mL U-100 scale. Check the actual device, markings, and prescription with a healthcare professional before measuring a dose.

The HCG calculator does not choose a diluent, mixing volume, preparation method, or injection frequency. Follow the instructions for your own product. Vial yield and TRT days of supply are mathematical estimates, not expiry dates or permission to keep using an opened or prepared vial. Estimates do not account for draw loss, syringe dead space, measurement error, or sterility. Follow product-specific storage and discard instructions.

Displayed results may use fewer decimal places than the underlying calculation. A rounded display is not an instruction to round your administered dose or select a syringe marking. Confirm a practical, measurable volume with your prescriber or pharmacist. The syringe illustration is a visual aid, not a measuring device.

The tool is provided as is. We do not guarantee that results are complete, appropriate, or error-free for every situation. Use is at your own risk. If you have medical symptoms or an emergency, seek urgent medical care.
