Still my favorite

One of the protein supplements that doesn’t give me gastric distress. I love the taste, too.

Better Than Premier Protein 30g High Protein

I first tried Premier Protein 30g High Protein. It was very good but this is better. It tastes better, mixes better, costs less.

Why sucralose?

Sucralose, really? Rather have a non-flavored protein powder. This powder is way too sweet.

For a sucralose-free alternative, check out naturally flavored Gold Standard 100% Whey from our shop page!

Why is a premium brand product artificially flavored?

Best of the best

I’ve only ever bought Optimum whey protein, variety of flavors that do not disappoint. Tried and true 100 percent. It’s the best protein to mix with oats, Greek yogurt, etc. IMO
