Ascent from Costco, it’s a lot cheaper than it is direct from them or Amazon.. I do add in a smaller bag from Amazon of one of the other flavors so I’m not stuck with just one flavor..

Ascent is the only one that doesn’t have an artificial taste.

I’ve tried all the ones our Costco carries. I wouldn’t call Ascent delicious but it’s less sweet and fake tasting than the others.

I love Legion and Ascent protein powders. Legion is more expensive but has lots of great flavors and doesn’t give me gas. Ascent is sold at Costco - I get both vanilla and chocolate.

Not my favorite in terms of taste. Recently did my own taste test and this is the order I ranked Vanilla. Dymatize ISO 100 9/10 ON 8/10 Ascent 6/10 Levels 5/10 Muscle Milk 4/10 That said, the macros are good and the price is good. I mix it with peanut powder and I like it much better that way.

Ascent or the Naked line are good.  ON has tested profile for heavy metals frequently and is just not a good brand if you’re concerned about quality. *“A 2026 Consumer Reports investigation found that Optimum Nutrition (ON) Serious Mass whey protein powder contained 8.5 micrograms of inorganic arsenic per serving, exceeding their suggested daily safety limit.”*
