Caffeine (200mg): Extracted from coffee beans, caffeine is a central nervous system stimulant that blocks adenosine receptors, reducing fatigue and increasing alertness. Scientifically shown to enhance strength, endurance, and training output. L-Citrulline Malate (4g): A natural amino acid found in watermelon, citrulline converts to arginine in the body, which boosts nitric oxide production. This relaxes blood vessels, improving blood flow and nutrient delivery — leading to skin-splitting pumps and better endurance. Beta-Alanine (3.2g): A modified amino acid that combines with histidine to form carnosine, which buffers lactic acid in muscles. This delays fatigue, allowing you to push past your normal limits. Choline Bitartrate (400mg): A nutrient related to the B-vitamin family, choline supports acetylcholine production - a neurotransmitter crucial for focus, coordination, and mind-muscle connection. AstraGin (50mg): A patented extract of astragalus and ginseng, clinically shown to enhance absorption of amino acids, vitamins, and minerals. It ensures every ingredient in YEAH BUDDY hits its maximum potential. Synergy: Caffeine drives your energy, citrulline opens up blood flow, beta-alanine extends endurance, choline sharpens focus, and AstraGin makes sure your body absorbs it all. Together, they create an unstoppable pre-workout formula that hits on every performance pathway: energy, pumps, focus, and endurance.
