Workout pumps; Exercise endurance; Strength and power; Focus without stimulants
Active adults who want a caffeine-free pre-workout for training days and people focusing on pumps and endurance without stimulants.
Mix 1 to 2 scoops with 6 to 8 oz (170 to 250 mL) of water per scoop and take 15 to 30 minutes before exercise; start with 1 scoop to assess tolerance, and note beta-alanine tingles are common. Pre-workouts with nitric oxide support may be taken with a light snack if you experience stomach sensitivity.
Gluten Free; Soy Free; Sugar Free; Vegan Friendly; Caffeine Free
Citrulline is converted to arginine and nitric oxide, which may relax blood vessels and support increased blood flow to working muscles.
Caution: May cause stomach discomfort in some people at higher doses; start with 1 scoop to assess tolerance.
Betaine acts as a methyl donor and osmolyte, which may support cellular hydration and muscle power output during intense exercise.
Caution: High doses may cause stomach upset; hydrate well to support its osmolyte function.
Beta-alanine combines with histidine to form carnosine in muscles, which may buffer acid buildup during high-intensity efforts.
Caution: May cause temporary tingling of the skin (paresthesia), which is harmless but can feel uncomfortable.
Arginine serves as a substrate for nitric oxide production, which may support vascular relaxation and nutrient delivery to muscles.
Caution: Can cause gastrointestinal discomfort in some users; avoid on an empty stomach if sensitive.
Taurine helps regulate cell hydration and electrolyte balance, which may support endurance and muscle function.
Caution: May have a mild calming effect; combine with adequate hydration for best workout performance.
Citrulline and arginine both feed nitric oxide production through complementary steps, supporting blood flow and nutrient delivery. Beta-alanine targets intramuscular acid buffering, while betaine and taurine support cellular hydration and muscle function. Together they cover blood flow, buffering, and hydration pathways for training performance.
Label Warning: For healthy adults 18+. Not for pregnant or nursing individuals, or those sensitive to beta-alanine. Consult a qualified healthcare professional before use, especially if you take medication or have a medical condition. Stop use and consult a professional if any adverse reaction occurs. Temporary skin tingles may occur.
Who should be cautious: People with sodium-restricted diets may wish to monitor total sodium. Individuals with cardiovascular concerns or blood pressure issues should discuss use with a healthcare provider. Those taking medications should consult a healthcare provider before use.
