I purchased the collagen peptides and collagen protein(vanilla) I am disappointed in the flavor of the protein. It had a very bad after taste and makes me not want to drink it. I added peanut butter to it and it helps but I cancelled my subscription because I cannot do the taste. I am happy with the peptides because it is legit flavorless. I mix it in my coffee in the morning and I can feel a difference in my energy and even joint pain. My legs constantly hurt from nerves and back problems but this helps with some of the pressure in my joints. I will most likely continue with the peptides because I am pleased with what I feel so far.
