Xtreme Mass Gainer – Analysis

Xtreme Mass Gainer is a hypercaloric supplement from the Xcore Nutrition brand and is one of the best selling products in its line in Portugal.

For those unaware, a hypercaloric/gainer supplement serves to help increase muscle mass/weight.

We will review the supplement through its label and the benefits proclaimed by the brand in relation to the product in question.

The brand highlights:

  • 1315 calories without sugar or aspartame
  • 50g of high quality protein
  • Inositol
  • Creatine
  • BCAA's
  • Glutamine

The supplement is available in a 2.7kg bucket and in a larger 5.4kg version and prices are around 25-35? and the 40-50? respectively.

We will now analyze this supplement in more detail.


Looking at the label, we see that the main source of protein in this supplement is isolated soy protein, a medium-low and cheap quality protein, never being a first choice in terms of quality as a protein source.

We also find milk proteins, quality proteins and egg protein, which is also an excellent source of protein, however, wheat protein is another of the main sources of protein in this formula, which makes it a weak mixture.


77g per 100g

258g for every 5 scoops

Extremely high values, which makes us wonder if we are not simply buying a carbohydrate supplement.

The source of these same carbohydrates is maltodextrin which, although not listed as sugar, has a very similar action, being very similar to dextrose / glucose with extremely fast absorption.

A good choice in the post-workout and that's it.

Residual values of fat, therefore, there is not much to comment.


A huge variety of vitamins and in interesting amounts, for those who do not use a multivitamin is an interesting addition.

Regarding the highlights of the brand: 

BCAA's ? There is no addition of BCAA's (Leucine, Isoleucine or Valine) listed in the ingredients, so we assume that the brand only tried to use the fact that milk and egg proteins include BCAA's to create a ?false illusion? of a formula with added BCAA's.

Creatine ? 300mg of creatine per 100g and 1g per full serving (5 scoops) is simply a low dose.

Glutamine ? 150mg for every 100g of product and 500mg for every full dose (5 scoops), this is an incredibly low dose that will not provide any benefit.


Assuming the price is around 30? for the minor version and 45? for the most part, it is still a weak product, as 77% of the content is maltodextrin and only 15% protein, much of which is low quality and cheap.

To give you an idea of what you get with the Xtreme Mass Gainer:

In the 2.7kg version, approximately 2.1kg are maltodextrin and 400g protein (from a poor quality mix).

In the doses recommended by the brand (5 dosers) we have only 8 doses in the 2.7 kg version and 16 doses in the 5.4 kg version which means that in the first version the supplement lasts only one week.

On the positive side, we can highlight the vitamins it contains, but if we were looking for vitamins, it would certainly not be a hypercaloric our first choice.

To conclude, we do not recommend this supplement, there are hypercalorics with much higher formulas.
