BSN Syntha-6 Isolate feeds your muscles with pure Whey Protein Isolate and Milk Protein Isolate that is flavored with the same luxurious taste of the original Syntha-6. Whey Protein Isolate is regarded as one of the purest and leanest proteins that is rapidly absorbed and digested, giving your muscles an immediate supply of amino acids needed for growth and development. Milk Protein Isolate, on the other hand, is a slow-digesting protein source. Since it gets digested at a slower rate, your muscles will enjoy a sustained and steady supply of aminos over extended periods of time. Just like Whey Protein Isolate, it contains all the EAAs (Essential Amino Acids) and the BCAAs (Branched Chain Amino Acids) to fuel protein synthesis and support the growth of muscle mass. Syntha-6 Isolate features a precise 50/50 blend of Whey Protein Isolate and Milk Protein Isolate to give you both fast-acting and slow-digesting protein support for your bodybuilding needs. Syntha-6 Isolate acts fast enough to repair damaged muscle tissue immediately after exercise, and it follows through by ensuring a continuous supply of amino acids that lasts for many hours. Syntha-6 Isolate contains the same magical taste and texture of the original Syntha-6, loved by millions all over the globe. Each creamy serving will certainly have you longing for the next one.
