Calculate Target Leucine Doses
Determine your per-meal amino acid threshold based on lean mass and age.
AMINO ACID SYNTHESIS & LEUCINE TIMING
Hitting your daily protein goal is only half the battle. Distribution, leucine threshold, and digestive absorption dictate whether that protein builds lean muscle or goes to waste. Juno optimizes your protein timing.
How it works
Set up once. After that, Juno fits around meals, movement, reminders and the occasional 1 a.m. question.
Determine your per-meal amino acid threshold based on lean mass and age.
Avoid single massive protein dumps for consistent anabolic triggers.
Watch lean muscle retention improve while body fat percentage drops.

Derek was consuming 200g of protein daily, but chugging 100g in a late dinner. Juno showed him that muscle protein synthesis caps at ~40g per feeding and recommended splitting his intake into four 45g meals spaced 3.5 hours apart. His muscle fullness, pumps, and squat recovery improved noticeably within 14 days.

FAQs
Not bad at all! Your body will absorb all nutrients, but additional protein beyond ~40-50g is used for energy or oxidation rather than stimulating extra MPS.
Plant proteins work great when consumed in sufficient quantities or combined to reach the necessary ~3g leucine threshold per meal.
