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 who don't know, a hypercaloric/gainer supplement serves to help increase muscle mass/weight.

Let's 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 a larger 5.4kg version and prices are around 25-35? and the 40-50? respectively.

Let’s 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 quality and cheap protein, never a first choice in terms of quality as a protein source.

We also find milk proteins, quality proteins and egg protein 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 leaves us wondering if we are simply buying a carbohydrate supplement.

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

A good choice post-workout and just that.

Fat residual values, therefore, there is not much to comment.


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

Regarding brand highlights: 

BCAA's ? No addition of BCAA's (Leucine, Isoleucine or Valine) is listed in the ingredients, so we assume that the brand was just trying 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 weak dose.

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


Assuming the price is in the 30s? for the smaller version and 45? for the largest, it is still a weak product, since 77% of the content is maltodextrin and only 15% is protein, much of which is of low quality and cheap.

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

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

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

On a positive note, we can highlight the vitamins it contains, but if we were looking for vitamins, a high-calorie product would certainly not be our first choice.

To conclude, we do not recommend this supplement, there are high-calorie supplements with much better formulas.
