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.
