Yummy. Very yummy and filling. Has high cholesterol tho. Will be switching to vegan protein only for that. My 17yo son will enjoy it moving forward. I recommend for sure otherwise *

If you know you know. I enjoy having a little dessert for breakfast sometimes feels like a little incentive to start my day with a shake.. Plus I like the consistency if this product always blends easy no clumps so it’s easy to get down when drinking it. Been using this brand of protein about a year and have put on a fair bit of size due to it.*

Rule 1 is about the only protein I go for anymore. The price, mix ability and taste is a tough combo to beat.*

Burst of flavor and the smell is amazing. A lot of powders tend to have a synthetic smell and this one smells like those scented candles you get at home goods. Blends very well with oats, excellent texture and feels great after digestion. 10/10 my favorite brand and i’ve tried 20+ different brands. The only thing that comes even remotely close is dymatize iso100 protein isolate when it comes to flavor.*

Great product. Great flavor. Never thought I would enjoy a fruity cereal flavor thinking it would have an off taste or be too sweet - but this blend tastes right on the money like the real deal.*

I’m pretty sure I’ve gotten the Fruity Cereal before and absolutely loved it, that’s not the case this time though. All I’m getting is a super strong lemon taste from this order. Still gets a 3 for the macros but definitely won’t get that flavor again*

Rule 1 has become my go-to protein. Its one of the cleaner products' out there, if that is something you are concerned with. The flavors are great, and they mix well. I have also mixed the S'mores protein with coffee, and its pretty awesome!*

Rule1 protein is a great tasting and mixing protein. But on the other hand time in transit from muscle and strength through FedEx, ground is absolutely atrocious. I will no longer be ordering this product through muscle and strength. I will find an alternate company who has a mentor delivery service.*
