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, and a free testosterone estimator using the same formula private clinics use.
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.
