Protein Powder, Low Carb Whey Isolate with Vitamin C & Zinc for Immune Support, 25g Protein, Keto Friendly, Chocolate Peanut Butter, 40 Servings, 3 Pounds (Packaging May Vary)

One of the worst protein powders I’ve tried in my life - waste of my money, it doesn’t mix well and the taste is beyond plastic and horrible! I threw mine away - and this has 25g protein only as compared to many other leading ones offering 30g - certainly peanut butter chocolate flavor is the worst one this brand has!

I’m on a low calorie diet and this protein powder helps me hit my protein macros every day. My husband adds it to his coffee every morning. I drink it hot. I know that sounds weird but I don’t drink coffee so I mix this with warm water in the morning and drink it. It’s not foamy!!! It’s high quality and isn’t gritty. It’s expensive but you’re paying for the quality so it’s worth it to me.

I really like this protein powder. It mixes smoothly and tastes great, not too sweet or artificial. I’ve noticed it keeps me full for a long time and fits perfectly with my low-carb goals. It’s been great for helping me hit my protein target without adding extra sugar. Definitely one of the best protein powders I’ve tried, and I’ll keep buying it even though the it got alittle pricier lately.

I was a customer of isopure for 10+ years. I always recommended them to friends looking for a good protein. Recently it looks like they changed their look but I never saw a mention of change of formula. The powder is gritty, and doesn’t dissolve as well as it used to. The texture is just off now. The calories per serving has changed as well as the size. Flavor is just okay and macros are still good. Just not happy with the sudden change of texture. Edit 8/16/25 I reached out to the company and after sharing my concerns I was informed they’re releasing an updated formula this month to remedy the gritty texture. They were gracious enough to also send me a free tub of this updated formula. I will continue to be a fan of Isopure and recommend it to anyone looking for quality protein supplement.

High protein, low-carb & low-calorie. Chocolate peanut butter is the worst flavor in my opinion, I like the toasted coconut and the double Dutch chocolate which are my favorites. This, IsoPure is my go to daily shake in the blender. It’s allowed me to both lose weight and gain lean muscle mass at the same time. That’s the Holy Grail🫡

Yes, this is advertised as chocolate peanut butter but the taste is not exactly peanut buttery. Oh no. The reality is so much more. I expected something that taste in the vicinity of a peanut butter cup. What I got was a blast of Nutella. I don't know why but to me this tastes like liquid Nutella. There's the obvious dominant flavor of chocolate but there is a definite streak of hazelnut flavor in here. The combination, as I said, creates the overall impression of sucking down Nutella. All I can say is: It. Is. Glorious. Nothing this healthy should taste this good. I'm serious. I look forward to this shake every day. As an RN, I'm on my feet and lifting or turning patients all day. This constant activity places a heavy strain on the body. This shake packs a protein punch to keep my muscles fueled and delivers a jolt of flavor that gets me through the day. Plus it's incredibly convenient. There are times when your lunch break gets cut short but with this shake I know I can get everything down quickly and feel satiated throughout the rest of the day. This isn't just a good meal replacement/supplement for when you have to get nutrients down in a hurry, it really has helped with my training and I've noticed tangible gains since using this product. Right now I'm programming with the Strong 5x5 routine. At first I was just using basic whole foods to meet protein needs however as I progressed I found myself taking longer and longer to recover fully. That's when I decided to try a protein supplement. I had tried others in the past. They were usually gritty and would mess with my stomach. So I did a lot of research on the best protein powders out there and this product came up. I can tell you that not only is my strength increasing at a steady rate but my muscles are growing in size as well. The extra boost of protein this shake provides has definitely been helpful in making and maintaining gains and we all know that it's all about the gainz! The texture isn't too bad either. There's a bit of grittiness and aftertaste but no more so than if you actually ate a spoonful of Nutella. The grittiness is certainly better than other powders I've tried. I don't think you'll ever find a perfectly smooth protein powder but this is very easy to take. Plus, the resulting shake is thick and gives you the feeling that you're actually eating something. Overall, I absolutely recommend this shake. There are no real drawbacks to using this as a supplement. The taste, while not exactly as advertised, is serenipitously delicious in its own way and their failure to perfectly capture the flavor of peanut butter has resulted in something even more amazing. So in short, taking your Isopure protein, move some iron, and make some gains!
