APS Nutrition's Chain'd Reaction is a BCAA (Branched-Chain Amino Acids) supplement with a focus on the scientifically proven 2:1:1 ratio of BCAAs, which stands for Leucine, Isoleucine, and Valine. These amino acids are essential for muscle growth and recovery, making BCAA supplements popular among athletes and fitness enthusiasts.One unique feature of Chain'd Reaction is the utilization of a time-releasing matrix through APS's Micro-Rx and Extend-Rx technologies. This technology allows for the slow release of L-Leucine, one of the key BCAAs, over a period of time. This extended-release approach could potentially provide a more sustained supply of Leucine to the muscles, which can be beneficial for muscle protein synthesis.In addition to the BCAAs, Chain'd Reaction also contains Glutamine, another essential amino acid. Glutamine plays a crucial role in various bodily functions, including immune support and gut health, and is often added to BCAA supplements to enhance their benefits.

Other Ingredients: Along with Leucine, Isoleucine, and Valine, APS Nutrition added Glutamine and a high dose of it. They also added Sustamine.
