Perfect

Triple chocolate isolate has a great taste and mixes extremely well in a shaker. Sometimes I mix it with plain Greek yogurt for a delicious pudding. Just add a little bit of water to the isolate first, mix for a thick slurry, then mix it in the yogurt.

Awesome flavour

Nice easy disolving protein. I had the strawberry flavour, and it was good mild flavour, no stevia metallic aftertaste. Sweetness was good, not too overpowering, when mixed with 1 scoop powder to 18 oz or 500 ml. about 2x recommended ratio. This is great for how i like to take mine. Lactose intolerant but this isolate protein is fine for me.

Amazing product, zero complaints

Bought this protein powder 2 weeks ago, and I’ve been loving it ever since. Blends super smoothly into milk and water, and has a beautiful chocolatey taste. The company was super responsive whenever I reached out, and the shipping was very fast. If you’re in the market for some clean protein powder with amazing flavour, I’d highly recommend!

Triple chocolate tastes more like a waffle

What a disapointment. I generally order Milk Chocolate and mix it wtih cocoa powder, so when I noticed Tripple Chocolate I thought this would be it. Instead, the taste is similar to KitKat, and it is a big disappointment.
I've given it 3 stars because it is still Diesel, and it mixes well.
