• 100% Uncoupled Aminos 
• Human Muscle Protein Complex™
• Animal Nitro™ Accelerated Amino Transport

Animal Nitro is the first and only supplement that contains the correct ratios of those aminos based on human muscle protein itself. This complex of aminos is appropriately called Human Muscle Protein Complex™ (HM PC&trade) and they're only in Animal Nitro. HM PC™ consists of special "uncoupled" aminos exclusively - those that are free of the chemical bonds that can limit maximum utilization.
