Whether you train morning, evening, or multiple sessions a day—it’s designed to support peak performance with pure pump technology.
L-Citrulline is known to increase performance among other benefits. Research in the Journal of Applied Physiology notes:
"In conclusion, this study has shown that short-term Cit supplementation can reduce blood pressure, speed V̇O₂ kinetics, and enhance endurance exercise performance. Therefore, the results of this study suggest that chronic supplementation with Cit might represent a practical, dietary intervention to reduce blood pressure and enhance oxidative metabolism and exercise performance in young healthy adults." (2015)
