How much leucine is in this? is it from grass fed cows?

There is 2,075 mg of L-Leucine per scoop. The cows are both pasture fed and fed with ingredients that may have been produced on other farms and feed mills. The cows are raised conventionally according to USDA or International dairy standards.

What is the self life of this product?

Klean Isolate is good through to the expiration date on the bag. Please store in a cool, dry place.

Why is this protein so expensive? Same ingredients as many others out there.

Unknown, I will say it burns clean but I wasn't willing to continue paying those prices. Check Opportuniteas they have a powder about half the cost

High quality, great taste, easy mixing.

My first time ever using a protein powder. Recommended by my sports doctor. Very happy with the ingredients (no artificial sweeteners), the flavor (I chose vanilla) and the mixing process. I add it in unsweetened almond milk and use a milk frother to mix for a few seconds (a fork also worked well). I highly recommend this product and hope it soon goes on sale so I stock up a few bags.

Well worth the cost

I'm honestly blown-away in regards to any negative comments about this product. Is it the very best tasting protein powder every? No, because it doesn't have all the added crap like the other ones do. Does it taste bad? Not at all. TIP: if you want some added protein & extra flavor, mix this with milk. It legit tastes like a chocolate milkshake! Phenomenal product. I would recommend it to anyone. It's definitely on the pricey side, but I think the quality you get is well worth the cost. Also - doesn't clump. I use a BlenderBottle with the metal ball. Zero clumps. Great source of protein!

taste is awful

I usually purchase Alaya Vanilla Whey. I decided to try Klean Vanilla Whey based on what I read online. The taste is just not good at all.

Excellent

I've tried so many different protien powders. I'm quite picky about how it tastes with just water and how it mixes in a smoothie. This is the best NSF certified, clean protein I've found. Tastes great plain and mixes really well in a smoothie. Also gives me no stomach issues like a lot of other protien I've tried. Will ve subscribing to this protien powder!

Would buy again

I use it in smoothies and don’t get a chalky taste. Flavor is subtle. Would buy again.

Good but pricey

I glad it doesn’t have the chalky taste like most protein powders but it’s a little sweet when just mixed with water. And I was thinking the bag would’ve been bigger for the price

It's good, tastes great, price is a bit high for the amount you get.

Overall I like it, the chocolate flavor tastes great better than the vanilla. No chunks when mixing it which is good. Smells good.I been using it for about 6 months and I like it compared to most brands , only issue with this would be the price for the amount you getBut I do recommend trying it.
