70% protein by weight is kinda low for isolate (25g/36g serving). Do all those fillers mean it tastes good? Also higher calorie - 140cal with 100 of those from protein, again high for isolate. But, sometimes those fillers make it taste better. I also generally prefer sucralose to stevia - tastes better, although I realize that is an unpopular opinion around here.
I like sucralose too

Watch out for the scoop on this. It's supposed to be 36g but 1 scoop weighed out to like 45g for me

Ive had this protein before. By far one of the best tasting ones I EVER.
Agreed. Any one who makes creami ice creams, this is an excellent protein powder for that.

The description free of artificial sweeteners, but sucralose and acesulfame potassium are clearly listed on the ingredient list. What gives? My go to is MyProtein whey isolate unflavored. Just pure protein.

This powder is less dense than Dynamize.

I tried to fit this 5lb bag of powder into an old/empty 5lb jug of Dynamize ISO100 (because I prefer jug to bag).

It didn't fit.

This powder is pure garbage, also contains lead. Levels grass fed whey is so much healthier don't skimp out.
I'm all about grass fed beef products and dairy. It's 90% of what I eat. Being grass fed makes absolutely zero difference for a protein isolate. It's pure protein. A grass fed diet effects the fat.

Also, this stuff has been regularly 3rd party tested, including by multiple 3rd party publications, and it has some of the lowest amounts of contaminants tested. Every supplement has to include the Prop 65 warning on their package because of California. It doesn't matter if the lead is well within safe levels (the protein you mentioned contains lead as well, as everything does), it still has to be there.

What flavor did you like?. I tend to like vanilla but it's hit or miss and I'm okay with chocolate if it taste better than bad tasting vanilla

Much better taste than most other whey protein
Tell us what flavor. It's pointless to just say this as a general statement

The good - Just received my order. First time purchasing this protein product. Loving the content and taste.
Bad news - Zip lock not working. Almost looks like its got same sides of the zip lock on both sides. No matter how much I try to zip the bag, its not closing. Had to move powder to my old tub.

I had to clear out the zip lock on my bag, a bunch of powder was pressed into it. After that it worked

Sure sorry. I'm drinking the vanilla right now. It's fine. The chocolate though was amazing.

Since it's an isolate, does that mean it's low in lactose?
Lactose is a sugar. Check the sugar content.

I'm lactose intolerant, it's fine for me so far.

Reviewer C.W. on Amazon. Rated it a 4 out of 5. He analyzed scoop across different brands: 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.
