ON's Amino Energy is truly an amino acid blend in a class of its own. Containing more than just the essential amino acids found in protein, it contains ingredients specific for sustaining an intense workout (such as Citruline and Beta Alanine often found in pre-workouts).
Amino Energy unlike other amino acid blends also contains caffeine, although not an amount that would class it anywhere near "high stimulant". The amount of caffeine in Amino Energy is intended for sustainable energy release for before, during your workout or just to drink throughout the day.
Amino Energy is now available in a convenient and cost-effective twin pack at Mr Supplement. Mix and match your favourite flavours or just double up on your one and only flavour and save.
