    • 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.

    Not the best not the worst

    Review posted on 11 Sep 2016

    The taste is excellent (Strawberry and cream). The actual product for carbs is great as its very high in carbs. The actual protein does not feel as effective because compared to isolated whey the effect of recovery is noticeably slower and reduced. Still decent value and still overall a good product

    Probably one the best tasting shakes I've had. I only ever order chocolate perfection. And I think Reflex have got it down to a T

    Great Product

    Review posted on 08 Feb 2016

    Comparing this to some of the other shake powder I have used in this past, I have experienced no bad gas like I have done with previous products, the taste is in my opinion, amazing if you buy the chocolate flavour, and the nutritional value is amazing as well. The only thing I would suggest when buying this, is if you plan on taking 1 serving per day, it will only last you a month, so if you plan on 2 servings a day, buy 2 bags to last the month.

    Best Protein Drink

    Review posted on 23 Sep 2015

    I have been trying numerous protein shakes & I must say Instant Mass Heavyweight checks all the boxes for me. Choco peanut butter tastes very good. The composition of 60g proteins, 200 g Carbs & less amount of sugar & fat make it an outstanding drink. I always used to have bloated stomach & farting problems with all the protein shakes I have used in last 1-2 years however, I never had such problem with Instant mass heavyweight. I gained 3 kgs in 3 weeks. Pros: - Best protein,carb, sugar & Fat combination in the market - Choco peanut butter tastes best (I tried chocolate flavour which was bit metallic in taste but Choco peanut butter is best & will stick to it) - No bloating problems - No Farting problems - Instant weight gainer. results will be visible in 1st week itself - Got 5% discount on second order. Will order 2 next time to get additional 8% discount - Free shaker in my first order - Able to lift more weights in gym now Cons: - a Fraction costlier - slightly sweet (probably due to sweetener added to it) but, sugar levels are very low. Sweetness can be adjusted by adding additional water or Milk. Regards :)

    I used to take Instant Mass & One Stop Extreme every day but came off it for a couple months. While off it I lost a stone in weight and people were asking me what happened. I decided to go onto Mass Freak but saw no gains. I am happy to say I am back with Reflex and will be sticking with them this time.

    Value for money on pack size. Bought the Chocolate and Peanut Butter and tastes really good. Seem to have put on a bit of muscle size but still quite lean. Tried other types of protein but this most enjoyable so far.

    How to gain weight rapidly !!

    Review posted on 05 Jun 2014

    I have been trying to gain weight for a couple of years I have a very busy lifestyle working on a agricultural stud farm starting work at 8am and often finishing around 8pm so burning lots of calories then one day a friend suggested that I tried a weight gainer so I started off using Mutant Mass this product was good for gaining weight but did not agree with my stomach so I decided to try a different product Reflex instant mass heavyweight chocolate flavour I have been using it for two weeks and have gained a stone in weight it tastes great and agrees with me so now I am going to order the vanilla and also the strawberry I would highly recommend this product for fast weight gain good luck :- Bryan
