Response time
BicepCalc is run independently, so replies come from a real person rather than a support desk. We aim to respond within a few business days. Please include enough detail (which calculator, what you entered, what you expected) so we can help quickly.
A note on the calculators
The tools provide estimates for educational purposes and are not a substitute for professional medical, fitness, or nutritional advice. For health decisions, please consult a qualified professional.
