I’m glad you asked. The active ingredients in Stim Free Pre Workout are Citrulline, BCAAs, Beta-alanine, Betaine, Taurine, Tyrosine, Choline, and Piperine.

  • Citrulline: the most powerful nitric oxide booster to drive up your nutrient delivery into the muscles, boosting endurance. This is also a potent pump booster and will improve your vascularity as well as muscle size during and after workouts. 
  • BCAAs: protect your muscles from damage and boost endurance with BCAAs. These also help support muscle growth and reduce muscle breakdown during your workouts.
  • Beta-alanine: a powerful muscle metabolism buffer that boosts endurance in the 1-5 minute range, letting you work harder for longer. This is perfect for athletes and bodybuilders, letting you work harder and boost results. 
  • Betaine: this can help you get better pumps, maintain muscle chemistry balance, and support post-workout recovery. A great choice to improve the power of citrulline and beta-alanine.
  • Taurine: a crucial cardiovascular support ingredient to max out your pumps and post-workout recovery, increasing circulation into tired muscles. This is a perfect synergist with the other ingredients in Stim Free Pre Workout.
  • Tyrosine: a great mood stabiliser to help you feel good while you workout, and reduce the onset of mental exhaustion. This is always a good addition for mental wellbeing.
  • Choline: a mental performance compound that helps boost Acetylcholine in the brain – responsible for memory and cognition. Choline levels ensure your brain has what it needs to function properly.
  • Piperine: the best absorption aid on the market, offering better uptake of key nutrients through the gut and into the bloodstream.
