• WolfTheCat:”The primary metric here is cost per gram of protein, because I figure that is what you want in protein powder. I also list:
  • The type of protein (Whey, soy, etc…). If it is a blend, I include the first two main components in order. For example Isolate > Concentrate means the blend is primarily isolate and has some concentrate.
  • The size of the container, in pounds. Some people don't want 15lb containers.
  • The percent of protein that is Leucine, considered the most important BCAA and a metric of a quality amino acid profile.
  • The percent of product mass that is protein. More mass-dense proteins have fewer ingredients that you may not want, such as inert ingredients, moisture, fat, and carbs (or, in some cases, heavy metals…).
  • The percent of calories that is protein. This is important for folks avoiding fat and/or carbs.”
