Review on Optimum Nutrition Gold Standard 100% Micellar Casein Protein Powder - Slow Digesting, Keeps You Feeling Full, Enhances Overnight Muscle Recovery, Creamy Vanilla Flavor, 4 lbs (Packaging Varies) by Riko Mizuseki ᠌

I tried this casein; the flavor profile isn't particularly complex, but it's certainly not bad. One 900-gram jar lasted me just under a month if I drank it every night before bed; it's effective, I suppose, but after a while I noticed that I was becoming immune to its effects and, on top of that, I found myself hungrier than usual in the middle of the night. In conclusion, you can purchase it if you are willing to spend the money; I paid $2,400 for a 900-gram jar.
