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 unfamiliar, a hypercaloric supplement / gainer 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 2.7 kg bucket and in a larger version of 5.4 kg and the prices are around 25-35 € and 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, so 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 - No addition of BCAA's (Leucine, Isoleucine or Valine) is 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 for every 100g and 1g for each full dose (5 scoops) is simply a low dose.

Glutamine - 150mg for each 100g of product and 500mg for each full dose (5 scoops), this is an incredibly low dose, which will not bring any benefit.


Assuming that the price is 30 € for the smallest version and 45 € for the largest, it is still a weak product, since 77% of the content is maltodextrin and only 15% protein, much of it being of 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, our first choice would certainly not be a hypercaloric.

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