Protein & Amino Acids
EAAs (Essential Amino Acids)
All nine essential amino acids in one product. Outperforms BCAAs for MPS because EAAs provide both the trigger (leucine) and the full substrate pool.

What Is EAAs (Essential Amino Acids)?
EAAs contain all nine amino acids that cannot be synthesised by the body — leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. Unlike BCAAs, which provide only 3 of 9, EAAs can sustain MPS beyond the initial signalling event, making them a superior choice when whole food protein is not practical.
How It Works: The Science
Leucine in the EAA blend activates mTORC1 to initiate MPS. The remaining 8 EAAs then serve as substrates for ribosomal assembly of muscle proteins — a step that BCAAs alone cannot fulfil. Studies consistently show net muscle protein balance with EAAs but not with BCAAs when protein synthesis is measured over extended periods.
Primary Mechanism
Direct MPS substrate provision + leucine signalling
Evidence-Based Benefits
Dosage Guide
Effective Dose
10–15g / serving
10–15g per serving, intra-workout or between meals. If you eat adequate protein from food and whey, EAAs provide minimal additional benefit. Most useful for fasted training or strict caloric restriction.
Safety Profile & Side Effects
Extremely safe. Individual amino acids at very high doses (pharmacological) can cause imbalances, but at supplement doses this is not a practical concern.
Who Should (and Shouldn't) Take It
Fasted trainers, athletes in deep caloric deficits, intra-workout use during very long sessions (>90 minutes), and vegans who cannot always reach protein targets from food.
