Ingredient highlights:

Beta Alanine

Start off strong and finish off strong too.

Beta alanine is a well reputable endurance supplement that increases carnosine stores in skeletal muscle tissue. Carnosine buffers acidic H+ ions that accumulate in muscle tissue during repeated muscular contractions, which helps prevent muscle pH from dropping too low, thereby delaying the onset of fatigue.

Beta alanine may help athletes to get more reps out and get more work done before reaching fatigue.


L-Tyrosine is a non-essential amino acid that plays an important role in the production of neurotransmitters dopamine and norepinephrine. In addition, because L-Tyrosine is necessary for the synthesis of thyroid hormone and epinephrine (adrenaline), L-Tyrosine supports healthy glandular function and stress response.

Research has shown this essential amino acid supports brain function including increasing mental focus and alertness, dopamine levels, mood and energy during exercise.

Focus on the workout, forget about what’s happening outside of the gym! 

Caffeine Anhydrous

Caffeine is the consummate pre workout ingredient, renowned for its ability to help boost energy, focus, mood, motivation, and performance.*

For these exact reasons, JACK HAMMER  includes caffeine anhydrous, to deliver intense and rapid energy.

Pure focus, energy and motivation!
