Kirkland Signature (Costco) - Whey Protein (Item 1780375)

Our Costco almost always has the Kirkland, ON, and Orgain plant powders for a great deal. Look for the 'Aussie Bites' in the snack section, the ingredients / protein is pretty crazy for the small bites.

I find Kirkland to be over the top for me. Doesn't mix as well so you have to mix with more water and drink more of it. The cream flavor is really strong and very artificial and I personally dislike that enough to stick with ON

I agree. Kirkland whey protein is an unbeatable deal. Second would be whatever protein Grocery Outlet has at the moment.

kirkland signature whey protein is $0.79 a serving

Blender bottle brand has a rounded bottom inside and its just easier/better. I love the costco Kirkland Chocolate Protein powder with PB Fit peanut butter powder mixed in. It's such a treat I look forward to it throughout my workouts lmao edit to add: I use the Kirkland oatmilk too, to mix it all together

Levels without a doubt. And it’s often on sale for $15 off. I’d say Levels >>> ON > Kirkland >>>> Ascent.

ON was best in that regard but I tried Kirkland and Levels AFTER I started GLP-1s and general gastrointestinal discomfort is a common side effect so it clouds everything a bit. I haven’t had any ON while on GLP-1s.

Personally, the Kirkland is the worst I've ever tried. It has such a strong artificial sweetener taste that made it such a chore to get through a giant bag of it. I should have just returned it.

I love the Kirkland whey powder, both the chocolate and vanilla. And it’s $1 per serving!

Costco’s Kirkland has better prices & is equal to optimum nutrition

Don’t fall for hype whey protein is whey protein for the most part Kirkland Way protein from Costco is gonna be the most efficient. It taste as good as any of the others and it cost at least 25% less than optimum. The general consensus is that the Kirkland whey protein and the optimum are exactly the same and manufactured by the same companies. I’m not 100% sure of this, but this is very common with Costco Kirkland products to have a high-end manufacturer produce a Costco branded product
