Looking for amino acids in their purest form? Meet PeptoPro! PeptoPro by XXL Nutrition consists of 100% patented PeptoPro®, which consists of more than 60% of pure dipeptides and tripeptides. This milk protein is pre-digested by enzymes, which means that it is split into very fine pieces (dipeptides and tripeptides). As a result of this splitting, the proteins are absorbed much more easily by the body, so that they can get to work immediately, especially around the muscles. No matter what kind of sport you practice; you always need protein. That is why PeptoPro is suitable for every athlete, from bodybuilder to marathon runner.

Even better than the best protein

At XXL Nutrition, quality comes first and that is why PeptoPro is the highest quality casein hydrolysate available. There are a lot of differences between hydrolysates, but you can't tell these differences by the nutritional values or the amino acid profile. The difference can be derived from the degree of hydrolysis: the degree to which the protein has been pre-digested into peptides. PeptoPro has a hydrolysis degree of no less than 28%, which on average is about 18% higher than many other producers. In other words, it is the most effective form of PeptoPro! 

Amino acids with good taste

A problem many producers run into is taste. After all, the higher the degree of hydrolysis, the more bitter the taste. After a long development process, we managed to combine a very high degree of hydrolysis with at least as good a taste! We have chosen the refreshing taste of Tropical Fruit. 

Usage and Dosage

Mix 1 scoop of PeptoPro (13 grams) with 250ml of fruit juice or another drink of your choice. Take 1 scoop before, and 1 scoop after the workout. After the workout, we recommend to combine PeptoPro with DextroJuice Pro or Waxy Maize and take a protein meal or protein shake after 30 minutes.

Do you also use the Essential Amino Stack? Mix 10-20 grams with a drink of your choice and consume it during the workout.
