1RM, RPE/RIR Auto-Regulation & 3g Leucine MPS Macronutrient Calculator

Calculate your true Epley/Brzycki 1-Rep Max adjusted for Reps in Reserve (RIR), prescribe working hypertrophy loads across 5–15 rep mesocycles, and model meal-by-meal protein dosing to cross the 3.0g leucine mTORC1 trigger threshold.

1. 1-Rep Max & RIR Working Load Prescription

Estimated True 1RM (RIR-Adjusted):269 lbs (122 kg)
Epley / Brzycki Model Split:270 lbs / 268 lbs
Optimal Hypertrophy Working Load:202–221 lbs (8–10 Reps @ 1–2 RIR)

2. Hypertrophy TDEE & 3g Leucine MPS Meal Planner

Daily Energy Target:3,260 kcal/day
Daily Protein (2.1g/kg Target):176g / day (2.1g/kg)
Per-Meal MPS Bolus (≥3.0g Leucine):44g protein / meal (~4.2g Leucine)
Daily Carbohydrates (Glycogen):470g / day (Glycogen & ATP)
Daily Dietary Fats (Hormonal):76g / day (Endocrine Support)

Biochemical Note: The 3.0g Leucine & Refractory MPS Window

Intracellular Sestrin2 dissociation and mTORC1 phosphorylation require roughly 3.0g of L-leucine per meal (~32–45g of complete whey, egg, beef, or poultry protein). Spacing 4–5 feedings 3.5 to 4.5 hours apart respects the muscle-full refractory period and maximizes 24-hour myofibrillar fractional synthetic rate (FSR).
