Single Peptide Calculator
Your original NYTE calculator is preserved below.
Blend Calculator
Mathematical concentration of each component in a blended vial. Not a dosing recommendation.
BMI Calculator
BMI is a screening measure and does not distinguish fat from muscle. Adult categories are not suitable for children or pregnancy.
Calorie & TDEE Calculator
Mifflin–St Jeor resting energy estimate multiplied by an activity factor.
The equation uses sex-based coefficients from the original validation data and may not fit every person. These are population estimates, not measured metabolic rates. Goal adjustments are starting-point illustrations, not individualized prescriptions. Monitor real-world trends and adjust as needed; pregnancy, adolescence and certain medical conditions require different guidance.
Healthy Weight Reference
BMI reference uses 18.5–24.9 for adults regardless of sex. The additional Devine ideal-body-weight estimate uses sex-specific coefficients and was developed for medication-related weight estimates, not as an individualized health target. Less reliable for heights under 5 ft (152.4 cm), muscular people, and some populations.
Body Fat Estimate
US Navy circumference method. Choose centimeters or inches for each measurement. Age does not alter this formula.
Circumference estimates are sensitive to measurement technique and are not equivalent to DEXA or clinical assessment.
