What are the benefits of SKULL LABS SKULL CRUSHER SHOT ingredients?

  • AAKG and citrulline malate act as NO boosters, influencing nitric oxide levels which may help increase blood flow, improve exercise capacity and reduce fatigue[1,2,3,4]
  • Beta-alanine is an important component in the process of carnosine synthesis - an increase in its content may have a positive effect on the regulation of acid-base balance, improvement of training adaptation or increase of neuromuscular efficiency[5,6,7]
  • Betaine supplementation during increased physical effort may prove to be a valuable support in reducing fatigue, improving body composition and some exercise parameters[8,9,10]
  • Caffeine has a stimulating effect on the nervous system, which may result in e.g. improved cognitive functions, shorter reaction times, improved attention and increased endurance during physical activity[11,12,13]
  • Taurine may work well as a form of additional support for the body during periods of increased psychophysical activity[14,15]
