TRT Dose Calculator

Divide the weekly dose by how many injections you do per week to get mg per shot, divide that by your vial concentration (mg/mL) to get millilitres, then multiply by 100 for U-100 insulin units. The calculator does all three for you.

Testosterone cypionate and enanthate are commonly 200 mg/mL, though 100 mg/mL and 250 mg/mL exist. Always read your vial — using the wrong concentration is the most common dosing error.

Splitting the same weekly dose into two or more injections generally produces steadier levels. The right frequency depends on the ester's half-life and your own response — confirm with bloodwork.

No. This converts numbers you already have. Your dose and schedule are decisions for you and a licensed clinician.
