Cleanest ingredients and best nutrition label Iโve found. No sweeteners! Doesnโt upset my stomach.
I searched through a LOT of protein powders until I found this, and Iโve purchased it several times. Very low calorie and high protein. Ratio is excellentโฆ25 grams of protein for only 100 calories! Most importantly, thereโs NO SWEETENER. Itโs nearly impossible to find a protein powder that doesnโt contain artificial sweeteners and flavors. Love that this truly contains only whey protein. Does it taste like a yummy milkshake? No. I blend it with strawberries, unsweetened yogurt, and high protein milk. I drink it with a straw, and it took some time to get used to the taste. However, I donโt expect it to taste delicious because I specifically wanted a protein powder without fake sweeteners and flavors.The fine powder blends really well, no grittiness. Itโs easier to scoop out of the 3 pound jar size, but the 1 pound bags take up less space. This protein powder is easy to digest and hasnโt bothered my stomach at all. Highly recommend if youโre looking for a very clean protein powder and are focused on macros and protein intake. Good quality.

Great Protein Powder!
This protein powder mixes very well and tastes great. It helps me meet my daily protein goals without adding extra sugar. I like that it is easy to digest and works well after my workouts. The quality is excellent, and I would definitely buy it again. Highly recommended!

Works for Me
I went to Gemini to get advice on what kind of protein powder to buy, and I got a list with advantages and disadvantages. I chose this for several reasons. It mixes easily and completely. It does have a slight taste, but when I put it in my Yeti and add ice to make it very cold, it's barely noticeable. I have not been mixing it in huge quantities, but 13g at a time which is the amount in their individual packets. I am using it to boost my protein as I am taking a GLP-1 to lose weight. I did learn this: if you accidentally spill a drop on your granite counter and do not notice it, it will harden to a waxy lump that needs special attention to clean. You have to be careful or you will damage your counter. Again, Gemini to the rescue, and we were able to remove the two lumps we had without damage. I usually use it twice a day, and I feel fine. My protein levels are good. I would like to have a 13 g scoop as well as the larger scoop, but I measure on a kitchen scale, and it's okay.

No taste! Does not mix with hot things.
This is a truly tasteless protein powder. Iโve cooked with it and have added it to drinks without it affecting the flavor or texture. The only negative is that it does not dissolve in hot foods or drinks. I tried adding it to my coffee and no matter how much I stirred/whisked it, it stayed clumpy. My workaround is that I mix it with my cold creamer and then add it to my coffee.

Finally, a Protein Powder That Doesnโt Ruin Your Food
Iโve tried a lot of protein powders over the years, and this is hands down one of the best. The fact that itโs truly tasteless is a game changer. I can mix it into literally anythingโcoffee, smoothies, even oatmealโand it doesnโt alter the flavor or texture at all. No weird aftertaste, no chalky feeling, nothing.What really stands out is how easy it is to stay consistent with it. Since it doesnโt overpower whatever youโre adding it to, it just fits into your routine without any effort. It mixes smoothly, doesnโt clump, and actually feels light compared to a lot of other protein powders Iโve used.If youโre someone who struggles with overly sweet or artificial-tasting proteins, this is 100% worth it. It does exactly what it claims without trying too hard. Simple, clean, and effective.

Blends easily. Tastes great!
Love this protein powder. Contrary to some reviews, this DOES mix well in coffee without the need for a shaker or blender. I dump a small amount of protein in at a time and stir after each time - no clumps and blends smoothly. It has a tiny bit of a milky or creamy taste and I think itโs delicious. I also add it to Greek yogurt bowls to get more protein.

Not terriblebut not a clear protein mix either
While no distinction flavor, there is still that milk type "background" taste unfortunately. I also experienced pretty prominent clumping even when using 16floz (recommended 6-8oz) which is unfortunate. This product was recommended as a clear protein mix and it most definitely is not

Good for upset stomach and lactose intolerance. No flavour no sugar, creamy.
Best power protein ever and I have tried dozens. I recommend. It is really unflavored and sugar free, which makes it easy to mix with almost any beverage or food. Itโs gentle to the stomach (good when lactose intolerance or upset stomach). Bring creamy smoothies. Less cravings. Clean ingredients. Good for men and women. Low calorie and high protein.

Best tasting protein powder EVER!
I absolutely hate the taste of non-sugar sweeteners in protein powder, tried a whole bunch of different brands. This protein powder, unsweetened, is surprisingly pleasant on the palate. Almost taste a little like milk. My favorite protein powder so far.
