ARNOLD IRON WHEY™ PROTEIN IS A HIGH-QUALITY FORMULA THAT DELIVERS LARGE AMOUNTS OF NATURALLY-OCCURRING AMINO ACIDS THE BODY NEEDS DAILY. Regardless of age or physical activity level, whey protein is essential for every nutrition regimen because it is the body's catalyst for muscle growth and protein synthesis. Trade up to a purer, more superior protein supplement that will help fuel your workout performance while also maximizing recovery time.*
WHEN MUSCLEPHARM'S WORLD-RENOWNED SCIENTISTS TEAMED UP WITH LEGENDARY FITNESS ICON ARNOLD SCHWARZENEGGER, THEY LOOKED AT HOW TO BRING A SUPERIOR WHEY PROTEIN TO MARKET.
And they knew the answer was "more." Specifically, they needed a higher protein formula to enhance nitrogen retention because muscles can only grow if a body retains more nitrogen. One of the most effective nitrogen sources is whey protein. To fuel more lean muscle development, our ultra-microfiltered whey delivers naturally-occurring anabolic amino acids directly to your bloodstream. This spike in aminos creates the nitrogen-rich environment needed for muscle protein synthesis. This is the key to building lean muscle.*
