How does Fortagen only have 5 calories?Updated a month ago

The 5 calories listed are not from the Amino Acids. They're actually from the other ingredients. 

The aminos themselves don't have a caloric value in the traditional sense. An energy value (calories) is assigned to amino acids, but not one relevant to human digestion, such as a measure of any standard macronutrient like a complete protein. 

From the perspective of an X3 user, the amino acids are not being used for chemical energy as they are being completely utilized for anabolic processes. Because no chemical bonds are broken when the amino acids are assembled into proteins, there is no real caloric energy released and, therefore, no traditional caloric value.
