best protein out there

this is genuinely one of the best protein powders i've tried. the flavor actually tastes good and not weirdly artificial or chalky and it mixes so smooth. i've been using it pretty much every day and it doesn't upset my stomach at all which is huge for me. it honestly just makes hitting protein way easier and feels like an actual treat instead of forcing myself to drink it. definitely gonna keep repurchasing

Rule1 is #1

[This review was collected as part of a promotion.] Rule1 Protein Source7 Birthday Cake is hands down one of the best tasting protein powders I've tried. The flavor actually tastes like birthday cake without being overly sweet or artificial. It mixes super smooth with water or milk and doesn't leave that chalky texture most proteins have. I've been using it daily after workouts and it keeps me full while helping me hit my protein goals. Huge bonus that it doesn't upset my stomach either. If you're looking for a great tasting protein with solid ingredients, this flavor is definitely worth trying.

Mix with cereal and almond milk!

[This review was collected as part of a promotion.] My pre workout meal lately has been pairing Rule1 Source7 protein milk chocolate flavor with cereal or oats. This helps satisfy my sweets tooth and love it in my weekly staple!! 🥰🥰😍😍My stomach is sensitive to ingredients, however have been using this protein brand for quite some time. Thankful for many options of flavors!!
