Review on 5 lb Promix Vanilla Grass-Fed Whey Protein Powder - Undenatured by Kent Page

I've been using Promix Unflavored Grass-Fed Whey Protein for almost 3 years. During that time I have made three different £5 orders. My first order arrived in a box almost three years ago (before they switched to tubes). There was no taste, it mixed very well. I could hardly tell it was there. Excellent material! My protein shake recipe is as follows: 12 ounces Califia Toasted Coconut Minmondmilk Blend2 scoops Promix1 teaspoon Hershey Chocolate Powder1 packet TruviaDash Espresso Powder Delicious blend! I finally ran out of my original order last fall when I started weightlifting in earnest. The second batch ordered was more yellow than the original and also a bit cuter (see attached photo, second order on the left and original order on the right). But it seemed to mix even better and even improve the flavor of my protein shakes. However - the amount of protein in each scoop has changed from 15 grams per two scoops to 25 grams per two scoops and the size of the scoop has also changed to a slightly larger one - see attached photos here too. My third order, which I placed last April, was a different story. If I had written a review last fall I would have given this product five stars. However, the batch I received in April was even paler than the first order, barely mixed, and also gave me diarrhea every day for a month! the time I started this new batch of Promix and initially blamed my stomach upset on it. However, I decided it was indeed Promix because when I got home I still had diarrhea on the days I took Promix and a happier stomach on the days I didn't. I have enjoyed using this product but the discrepancy is wide. worries me and I am very disappointed that I had a very upset stomach because of your product. I hope the manufacturer sees this feedback and fixes this issue. Like the previous recent reviewer who is also suffering from the same issues as me, I'm hoping it's just a random batch, but in the meantime I'm switching to another product from a different brand.
