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™ (HMPC™) and they’re only in Animal Nitro. HMPC™ consists of special “uncoupled” aminos exclusively – those that are free of the chemical bonds that can limit maximum utilization. By using only 100% uncoupled aminos in HMPC™, Animal Nitro delivers a precisely controlled dose of aminos that are “targeted” to efficiently enter systemic circulation through a novel amino transport system.
