Health Tools

Know Your Numbers

Free calculators for men who actually want to understand what's going on with their body. BMI, daily calories, macro targets, a free testosterone estimator using the same formula private clinics use, and an mg to ml dose calculator.

Tool 01

BMI Calculator

Body Mass Index. A rough guide, not the full picture, but a useful baseline. For men over 40, waist circumference matters as much as BMI.

Tool 02

Calorie & Macro Calculator

Built on the Mifflin-St Jeor equation, the most validated formula for resting metabolic rate in adults. Enter your stats, pick a goal, get your numbers.

Tool 03

Free Testosterone Estimator

Total testosterone alone is almost meaningless: it's what's free and bioavailable that matters. Enter your bloodwork values to estimate free T using the Vermeulen 1999 formula. Assumes standard albumin of 4.3 g/dL.

Tool 04

mg to ml Dose Calculator

Work out how many millilitres to draw for a given dose, and what that is in insulin-syringe units. Handy for TRT and peptide draws where vials are labelled in mg/ml but syringes read in units.
