L-Citrulline (4,500mg)
L-Citrulline is one of the most effective nitric oxide boosting ingredients, increasing blood flow and oxygen delivery to muscles. This helps produce stronger muscle pumps, improved endurance, and enhanced nutrient delivery during training.
Betaine Anhydrous (2,500mg)
Betaine functions as an osmolyte that supports cellular hydration, power output, and muscle performance, helping athletes produce greater force and strength during workouts.
Beta-Alanine (1,600mg)
Beta-Alanine helps increase muscle carnosine levels, which buffers lactic acid and delays muscular fatigue, allowing you to push through high-intensity sets for longer.
Taurine (600mg)
Taurine supports cell hydration, endurance, and electrolyte balance, helping maintain muscular performance during longer training sessions.
