Been using the native whey isolate for a few months and its become a staple. Dissolves with almost no clumps evn in cold water. Been through a bunch of isolates and this one mixes the cleanest for me.

Johns Killer Protein whey is the easiest way for me to hit my protein every day. Works great in both hot and cold drinks. Its the simplest way to get extra protein in without thinking about it. Definitely buying again.

Grass fed and native makes a difference compared to the cheap stuff. I throw a scoop in my morning coffee or smoothie and cant taste it at all.

Great product that I recommend to anyone needing a clean, digestible, and well absorbing protein. I add this to many meals to give my protein requirements a boost. The proof is in the pudding:)

As with all of John’s Killer Protein products, the quality is outstanding. Everything is pure and processed cleanly. Makes great protein shakes. I happen to combine it with their Nightime Casein, even though that’s not the norm. But I drink a protein shake I make from scratch with their products at least 3 times a week as my first meal of the day. I am not weight-lifting right now because of recovery from surgeries. But I couldn’t go without consuming my delicious protein shake 🙂
Here is my recipe: In a blender put 6 oz of certified spring water, 20 g Lean blend, 20 g Nightime Blend, 2 Tbsp organic, unsweetened cocoa powder (Lake Champlain cocoa is my favorite brand) and blend, then add 2 Tbsp organic grass-fed Half & Half milk, a couple of medium strong squirts of NOW organic Monk Fruit sweetener, a couple of squirts of one of Monin’s new sugar-free TruFlavour sweeteners – my favorite flavor choices at the moment are Hibiscus and Coconut and blend, then add 1 organic banana (75g appx), 40g organic blackberries, 40g organic blueberries and 75g organic strawberries and blend and then add 6 ice cubes made from certified spring water and crush them in the blender and pour into a 20-24 oz plastic chug bottle, and enjoy. Appx 400 cal, 42 g Protein, 46 g Carb, 7 g Fat *and* 45%-50% of necessary daily calcium <–thanks to the quality of John's Killer protein powders. Most friends I make it for love the taste.
