Body Weight Dosing
Body Weight Dosing — A dosing method where compound quantity is calculated per unit of body weight (e.g., mg/kg), the standard approach in preclinical peptide research protocols.
What Is Body Weight Dosing?
Body weight dosing expresses peptide dose per unit body weight (mg/kg, µg/kg, nmol/kg), normalizing for animal or subject size. This approach ensures equivalent systemic exposure across subjects of different sizes and is standard for preclinical and clinical peptide dosing. Species-specific allometric scaling converts doses between species.
Dose Conversion
- Mouse to human: Divide mouse dose (mg/kg) by 12.3 for human equivalent dose (HED)
- Rat to human: Divide rat dose by 6.2 for HED
- BSA normalization: More accurate interspecies scaling uses body surface area (mg/m²)
- Example: Mouse dose of 1 mg/kg = human dose of ~0.08 mg/kg (5.6 mg for 70 kg adult)
