A

Essential Amino Acids

Training Compounds

Mechanism

Provides the full substrate set required for muscle protein synthesis, especially useful when whole-protein feeding is constrained.

Contraindications

  • Use caution with advanced renal impairment
B

Leucine

Training Compounds

Mechanism

Branched-chain amino acid that directly stimulates mTORC1 signaling and helps trigger muscle protein synthesis when protein meals are under-dosed.

Contraindications

  • Use caution with advanced renal impairment
