It truly is #1

I have not found a casein powder better than this one. I have used casein powders as a pre-bed pudding mixture for several years now. Many mix too thin, others mix too chalky, and others lack real flavor. This one however is perfect. It makes a nice thick soft serve ice cream-like texture when mixing water or almond milk with 2 scoops worth and some frozen fruit (blueberries work very well with chocolate fudge flavor). It literally is the meal I eat daily that feels almost like a cheat when it's not one at all.

NOT MADE IN CHINA!!

Biggest + was made in USA! No special mystery ingredients like "Soylent Green" (younger gen can google that 1) from chinese brands. Been in/out Hospitals past 8 years; lost alot of muscle lying in beds... tryed this brand ist for above mentioned; seeing huge improvement in recovered mass and definition probably more so than the average joe/jill out there working out due to soo much loss of muscles and I've been going nuts on the max-out low reps weights ....to be honest maybe the others that have been on market for years work also...but am sticking with the good ole USA!

Amazing!

If you’re not mixing this with minimal water and making a thick icing like paste out of it and eating it on rice cakes, then you’re not living life. My coach has me eating 4 scoops a day so I’ve ordered about 40lbs so far and fixing to order more! Awesome!

Strawberries and Creme is delicious

I rarely use casein and I'm not a fan of strawberry protein in general but this is solid. I decided to try something new since the Apple Cinnamon in Whey wasn't available. I mixed it in Greek Yogurt and fell for it! I'm hooked. If the Cookies and Creme whey is as solid as this, Rule 1 may be the only protein I buy from here on out.

Salted Caramel is DELICIOUS

Buying protein before tasting can be a hit or miss. This salted caramel is amazing! Not only do I like the taste of this one, I like the thick, creaminess of the mixed consistency. The small size was out of stock (should have been my first hint that it was good), so I was a bit nervous when I had to order the large. I never imagined a protein would taste so good!
