Good Quality / Good Tasting Protein Powder

It is a very high-quality whey isolate.

Quality & Purity: It uses New Zealand grass-fed whey isolate

Macros: At ~110 calories per scoop, you get 25g of protein, ~0g fat, and almost zero carbs. That puts it at over 90% protein by calorie weight, which is top-tier.

Digestion: It is 99% lactose-free, soy-free, and gluten-free. If standard whey concentrate gives you bloating or stomach issues, this won't.

Flavour - I ordered the chocolate and it's quite good, obviously can't speak to the other flavors however there is also an unflavored version

The chocolate flavor is one of the better ones that I've tasted. The efficacy of the product remains in the trial stages but the pricing is encouraging.

Excellent taste, mixes perfectly, and easy on the stomach

I've tried quite a few whey isolates over the years, and this has quickly become one of my favourites. The Chocolate Ice Cream flavour is rich without being overly sweet or artificial, and it tastes great with both water and milk.

What impressed me the most is how easily it mixes. A few shakes in my bottle and it's completely smooth with no clumps or gritty texture. It also digests really well—I haven't experienced the bloating or stomach discomfort I've had with some other protein powders.

The ingredient profile is another big plus. Being grass-fed, low in sugar, and high in protein makes it an easy choice for anyone looking for a clean whey isolate. The quality feels premium, and considering the price for a 5 lb tub, I think it offers excellent value.

If you're looking for a clean, great-tasting whey isolate that mixes well and delivers what it promises, I would definitely recommend giving this one a try. I'll be buying it again.

Best taste ever

I had tried a variety of different protein whey isolates from progressive and other brands but this unflavoured tastes the best and dissolves well too. Being a Canadian brand is great so will stick on this brand henceforth.

A chocolate-lover's DREAM - crave-worthy!

I realize taste is subjective; however, I just purchased this protein for the first time & this is hands-down the greatest chocolate flavour I've had in my 20+ years of gym-going.

The fact that it's clean (ZERO artificial sweeteners, even - it's debittered Stevia!) and mixes flawlessly with water in a standard shaker cup (no clumping after 10-15 sec of vigorous shaking) caps it off perfectly.

The closest approximation of taste I can give is to picture a handful of Smarties candy-covered chocolates or Tim Horton's hot chocolate powder. It's that same rich cocoa, even on the finish/aftertaste.

(Like Dymatize's ISO100 Gourmet Chocolate, my previous high water-mark back in the day, before I became more aware of artificial sweeteners.)

Also - it's Canadian-made.
This receives my HIGHEST recommendation!
