Why is a premium brand product artificially flavored?

Why sucralose?

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

Don’t get scammed

You need this product ….So I’m back to update my review and I’m honestly seeing noticeable muscle gain now only a month in on taking this I have noticed that I feel more pumped recovering faster overall pretty happy I do however wish that they had more amino’s in this more complete, but I understand why they don’t I also wish that y’all offered an option that didn’t have sucralose or any false sugars in it if you have a version point me to that version cause I’d love to have it everything else I fully enjoy about this product except for your synthetic sugars no as flames no Sucralose no fake sugars not even Stevia use real sugar or let me sweeten hit myself with an option that doesn’t have this in it and you would have a great winter for me. But otherwise, I thoroughly enjoy this product

Great Product, Great Price

I love this and it works excellent in my protein shakes. Like to give it an hour for the whey to fully hydrate before drinking. Find this flavor of chocolate a little sweet but otherwise a great milk chocolate flavor.
