Great protein powder for regular
This whey protein isolate has a great flavor. If you regularly drink protein shakes, you might find artificial sweet flavors get tiresome pretty quickly. The flavor in this protein isn’t overly sweet and doesn’t have a strong artificial taste.

Very rich (sweet) flavor in a large scoop; mixes well and Informed Sport tested
This is the first time I’ve tried this powder as I’ve been looking for one I like at a reasonable cost with good protein:calorie ratio. With protein being about 4cal/g, that means this is around 67% calories from protein per scoop (100/150). Much of the extra calories come from the added MCTs since fats are close to 9cal/g, but in the limited research I’ve read, the benefits of MCTs are unclear. That said, this powder is DEFINITELY rich chocolate—it mixes thick in milk (which I then pour coffee into), almost like a shake, and is about as sweet as hot chocolate made by dissolving a chocolate bar instead of using powdered mix. The flavor is good, but many will definitely find it too sweet. I use a handheld milk frother to mix mine and very rarely have any clumps unless the whole scoop dives in at one time: it is a LARGE scoop at 106cc and even my frother struggles to mix it all at once. I’ve included a comparison pic to Rival Whey’s scoop (67cc) and Optimum Nutrition Whey Isolate’s scoop (70cc) for reference.I really like the fact that this brand is transparent about being third party-tested through the Informed Sport process and it is displayed prominently on the packaging. Not every company does this step so it gives peace of mind that what is on the label is in the product: so many companies skip the is step because of costs, or if they do test, they’re secretive about who does the testing, what they test for, and what the results are and that makes me wonder if the contents actually match what’s on the label (studies have shown that some powders contain less than HALF of the claimed protein amounts). That’s not the case here, so even if this isn’t the BEST protein, the cost is reasonable (~$1 per serving when I bought it) and I definitely feel like I can trust what is in it. Honestly, the testing is why I rated it 4 stars instead of 3, because it was a little bit too sweet for me (though perfectly drinkable) and the MCTs probably contributed to the “bubble gut belches” I experienced for about 10 minutes after drinking it if I wasn’t drinking it in my coffee throughout the morning.I may buy it again in the future, but for now I’m sticking to isolates with better than 80% of their calories coming from protein.

Delicious Vanilla Flavor
This vanilla was my favorite protein powder ever. It really is the first protein powder that I can honestly say is delicious. I really love it with 5 grams of powdered ginger added. It dissolves easily and mixes well in a blender or blender bottle. No gritty texture. A high quality protein and does not contain sugar or inflammatory sucralose. So sad that it seems like they stopped making it. Also, be aware that the chocolate which does seem to still be available does not taste nearly as good and does contain sucralose. I also like that it creates less plastic waste coming in a bag but I did pour into a reused plastic container for easier use.

CONTAINS LEAD (see consumer reports article)
Consumer reports just (October 2025) put out an alert on protein powders containing unsafe levels of lead.I’m normally an “ah whatever” kind of guy for things like this, but some products were containing like 1000% more lead per serving than one should consume per day!I looked at the back of this bag and sure enough, there’s literally a warning on it about lead!!!!! My dude, there are protein powders that do not *literally warn you* that they contain lead. Buy one of those. SmhAdditionally, it DOES NOT list any reputable third-party certifications like USP Verified, or Clean Label Project.They are intentionally misleading you by putting unrelated labels under “quality matters”. What does “gluten free” have to do with quality? Nothing.Do yourself a favor, look up “consumer reports protein powders lead” and pick one of the products they tested that contains safe levels.

Great taste, dissolves completely, and is the only Whey Protein Isolate that I could find that has vitamin D3.

I was excited about this but then it was so sweet I couldn’t handle it. I tried it simply with water and also with yogurt … way to sweet for me and I know that the sweetener in this will eliminate the benefits of protein.

One of the best tasting powders i have tried. I mix my whey with frozen fruits. Tired this with frozen strawberries, tasted like the chocolate strawberry ice cream bars.Texture is a grainy but i think its probably due to being an isolate. I usually buy whey blends which comes out foamy.Not sure how well it will mix without a blender but i always use a blender for any shake.

Flavour is on point, but the regular price is way too expensive. Its a great buy when on special. Mixes very well, good texture and not too much stevia aftertaste!

Very tasty. Have been looking for a good protein shake. I purchased the chocolate and mixed with milk. The perfect sweeteness
