  • Clean, high-protein boost - mixes well, no weird after taste
Flavor Name: Unflavored Size: 1 Pound (Pack of 1)
I've been using this unflavored whey protein powder daily for 2 weeks. I was specifically looking for something without any added extras so I can mix it into smoothies, homemade popsicles, and waffles without it changing the flavor of the food. What I like: • it mixes in pretty easily • it really is unflavored with just the faintest hint of dairy as you'd expect. • Great protein to calorie ratio. perfect for those of us on a GLP1 medication and watching our protein intake! • Minimal ingredients ... whey protein powder and sunflower or soy lecithin (keeps it in powder form) Things to know: • it's not 100% flavorless. No added flavors of course but it does have a faint taste of dairy as expected. • If you mix it with just plain water, it will look milky, not clear. • the scoop was buried. I guess that's to be expected. Shake the bag some and it will rise to the surface. I mostly use this in my iced coffee each morning along with some oat milk. Delicious and easily digestible, I will be repurchasing in the larger container. ... show more

  • Best protein powder out there!
Flavor Name: Unflavored Size: 4.5 Pound (Pack of 1)
I started with the smaller tub to test it out and was impressed enough to grab the largest size for better value. We prefer unflavored protein because it goes with everything , and you never get tired of it. I’ve used it for protein pancakes, boosted my Ninja Creami recipes, shaken it up with just water or milk, and blended it into milkshakes with other ingredients. Always smooth, no weird aftertaste, and zero carbs. ... show more

  • Clean Taste & Great Quality Protein
Flavor Name: Unflavored Size: 3 Pound (Pack of 1)
Clean taste, dissolves easily, and no heavy aftertaste like some protein powders have. I really like that it’s low carb and doesn’t upset our stomachs ( me & hubby). Perfect for shakes or even mixing into recipes. I make protein muffins for on the go in the mornings.

  • Big A** Bottle for a good protein Powder
Flavor Name: Unflavored Size: 4.5 Pound (Pack of 1)
F'ing huge. Its almost comical how large the big one is. In the photo the waterbottle is a Takeya 64oz with it. The product is amazing but I give 4 stars because it was NOT filled to the top. Its only filled to the label. Wish it was filled more. The taste is not completely tasteless but it blends well with my green smoothie. I like this because I personally am not a fan of the flavored protein powders. I get more than enough of my daily protein intake with it so I am glad about that too. Overall, wish they gave more given the price, but the product itself is soooo good. ... show more

  • Makes great latte
Flavor Name: Unflavored Size: 3 Pound (Pack of 1)
Great product! Mixes well in smoothies and cold drinks with no taste. It clumps heavily in hot drinks. I use it every morning to make cold latte by mixing six ounces of cold coffee with six ounces of milk. I stir it hard with a fork and then add six ice cubes and stir more. Can add a packet of stevia or a teaspoon of honey for a sweeter taste. It’s really yummy! The product also foams if the mentioned ingredients are put in a blender. ... show more

  • — “Clean, Effective, and No Nonsense”
Flavor Name: Unflavored Size: 3 Pound (Pack of 1)
Isopure delivers exactly what I need — high-quality protein with zero carbs and no unnecessary fillers. It mixes easily, tastes great (especially the vanilla and chocolate), and doesn’t leave me feeling bloated. Perfect for post-workout recovery or a meal supplement. I trust the ingredients and love that it’s transparent about what’s in it. Simple, clean, and effective. Highly recommended. ... show more

  • Dead spider inside brand new container!
Flavor Name: Unflavored Size: 3 Pound (Pack of 1)
I've been buying Isopure for a few years now. I've never had any issues other than the price going up tremendously during COVID and never going back down. I do like that the 1 scoop needed for 25g of protein is smaller, where most other powders, the scoop is huge. It's silky and smooth and mixes well for me, where other products do not. The unflavored is truly unflavored to me as well. However, I experienced something today that still has me grossed out and scares me regarding continued use. I came up on a great deal, buy1 big tub get a 2nd at 50% off. I opened one of the sealed tubs just today. I took a scoop and gently tapped it on the side of my coffee cup to sprinkle the powder in little by little while I stir it in the coffee to ensure it mixes well. I do this until the powder is all gone every day. But today, while doing this, I noticed at one point the powder on the edge of the scooper looked stringy, (hard to describe) like the powder had a tiny fuzzy on it but it was so tiny that I disregarded it, shrugging it off as possibly thicker powder or something and kept on sifting and mixing Next, I saw a dark colored object fall from the scooper, into the cup along with the powder. I scooped whatever it was out of my coffee and it was a dead spider. I poured the remaining powder that was in the scooper onto a paper towel to check through it and there was also a piece of wobbly filmly/ subtance covered with the powder in there as well. I went through Amazon customer service chat that promptly refunded the jug I bought for 50% off, no questions were asked. I was ok with that initially but I am unsettled after thinking more about it because I feel like I can't use the product anymore because I'm so grossed out and do not trust the quality assurance of the company and their product now before it gets sealed and final packaged. I can't use the brand new jug that was partially refunded because it's contaminated obviously but I'm scared to use the other brand new jug now as well, I'm afraid to and it makes me feel nauseous thinking about what if this container has bugs in it also and I consume one unknowingly and how many times could this have happened before over the years and I didn't know and feel I should be compensated for the other container as well. This stuff is not cheap and at almost $70 for one container, it shouldn't be wasted. Prior to this happening, I'd recommend this over all others but now I just can't. Maybe their customer service will reply to my messages to help with some way to make it better for me but as for right now, I can't support this product any longer. Not clean ingredients. ... show more

  • Not flavorless!!!
Flavor Name: Unflavored Size: 1 Pound (Pack of 1)
Great for post bariatric protein needs, but it’s definitely not flavorless and has a noticeable aftertaste.
