Heavyweight High BV Quattro Protein Complex provides a massive 60 grams of protein. Arguably the most sophisticated and best protein blend in a weight gainer that you wont find in any other product. Quattro is unique to Heavyweight, exclusively from Reflex Nutrition. It consists of three different types of whey protein in conjunction with pure undenatured micellar casein. Four of the best!

Quattro protein complex is one of the best combinations of protein science has to offer specific forms of whey protein and micellar casein.

However, we dont use just any type of whey proteins for Heavyweight, first we use two different hydrolysed (pre-digested) whey proteins; one has a High DH (degree of hydrolysis meaning how much its been pre-digested) which the human body can absorb almost instantly, the second has a Low DH providing the human body with a secondary hit of whey peptides. We use a preferentially selected whey protein concentrate in conjunction with unique native whey protein isolate that is chosen for its high levels of bioactive fractions and superior branched-chain amino acid (BCAA) content.
We add pure ultra-filtered micellar casein that is digested over a longer period of time feeding your body with essential amino acids for up to 4 hours providing excellent anti catabolic activity.

Nice change from my normal weight gainer. Very happy with the additional protein and CREAPURE Creatine. Mixes nicely but you need a big shaker! Tastes amazing, especially the chocolate.
