Heavyweight delivers in 5 key areas where other weight gainers simply do not.


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 won't 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!


What is Quattro® Protein Complex?


To trigger new muscle growth you need to train hard and consume the best high quality sources of protein. 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 don't 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 it's 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.

Third, 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.

Fourth, 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.

Note: Does not contain soy protein like some brands, soy has a lower biological value compared to whey.
