ProMix Nutrition Native Whey Protein Isolate Powder Concentrate: Standard 100 Percent All Natural Grass Fed & Undenatured ­Best Optimum Fitness Shakes & Energy Smoothie Bowls: Unflavored 5lb

Just because this whey is "unflavored" does NOT mean it is tasteless! If you have never taken a spoonful of whey from plain yogurt, do yourselves a favor and do so! You will realize that this liquid has a taste to it and personally I do NOT like eating it by itself! HOWEVER the whole purpose of me purchasing this whey for the family was so that we could enjoy some nutritious shakes etc. We purposely do not buy flavored whey as we do not want the list of ingredients that comes with it, preferring to add our own. Chocolate, caramel, strawberry...... the choices are limitless. Mix this grass fed whey with some almond or cashew milk, sweetener and flavor of choice plus some ice and you will NEVER know the whey is in there. Trying to drink it by itself? Quit torturing yourself! I researched for many hours and read many reviews before deciding on this GRASS FED Whey Isolate. I knew I was risking it by ordering 5lbs the first time around but decided to do so anyways. What pushed me towards this one? If purchasing beef we like to purchase grass fed as not only do we prefer the taste but also believe it to be better for our health. Yes, I realize that whey does not come from the meat of a cow! We also believe that grass fed milk is better for your health thus deciding on this whey. We have NOT been disappointed! 5lbs is a LOT of whey. It comes in a large plastic bottle with screw on lid. (Sealed on outside and inside for double protection.) Height of bottle is almost 11 1/2" and the diameter at the base is 7 1/4". The bottle is nearly full when it arrives. This whey appears to be a well made, verified product (you can read all the nutritional information in the listing) and we have used it many times. Highly recommended. We purchased this at the full prevailing price. We were not required to write a review but chose to do so. Thanks, Liz

High quality stuff. I've been using this for a few months now, and I can tell based on my body composition that it is high quality protein. It dissolves well in water or juice using just a spoon to mix. It tastes like plain dairy whey, which is to say it has a strong milk-like taste. It's not entirely unpleasant, but not delicious either. For me, that is a fair trade for knowing I'm using a clean, grass fed product without artificial sweeteners and flavors. This is best with juice IMO, but OK with water when watching carb intake. I use 50g first thing AM and 50g post-workout, and never have any bloating from it. I strive to use protein powder for not more than half of my daily protein intake, but I have had a few days when I've used this for all 225g of my daily protein due to time constraints, and still no bloating. This is one product I will continue to buy. It is a good choice for people who have concerns about additives in their diet.

Once I got it home, I found the flavor to be okay—I’m not disputing that. But I realized that the Naked brand Iso protein has more amino acids per serving. When you compare servings, both brands say that two scoops equal one serving. But when you look at each serving, you’re getting significantly more amino acids from the Naked Whey Iso compared to the Promix. What’s even more confusing is that the Promix scoop is almost twice the size of the Naked scoop. That makes me wonder if there are fillers in it, because I don’t understand why the scoop would need to be so much bigger while delivering fewer amino acids. I don’t think I’ll be buying Promix again. Based on what I’m seeing, the Naked brand Iso offers better value and quality of protein. I’m glad I tried it, but after seeing the scoop size and comparing them side-by-side, I won’t be purchasing Promix again.

I have used Promix isolate and concentrate for several years and had no issues. Promix still a value? Many products have gone up in price some far more than others. I have tried to leave an honest review but it keeps being rejected.

Good product but ever since they raised the prices its been over priced, naked whey is a lot better in terms of cost though even that is still expensive.
