Really good protein powder/meal replacement. I have the chocolate flavor and mix it with 10-12 ounces of cold water and it tastes really good. I have been taking 1 scoop of this in the morning along with eating a banana before my 6-9 mile walk and it keeps me full and energized throughout the entire walk. I am not a runner but i am not just out for a "causal" walk either. I speed walk the entire time. I just finished a 2lb tub of it and just purchased another 4lb tub. Will buy again when this runs out and highly recommend giving it a try.

Highly recommended. This product is by far surpassed all my expectations. The flavors are excellent (chocolate & cinnamon churro). I only use 400ml of water, its so tasty and the texture is rich & creamy. I used this 2x a day as a meal replacement. It keeps me full for like 3-4 hours. In between, I have a handful of berries and an apple or orange as a snack. My bowel movement becomes regular. My gas problem lessen and bloated feeling is gone. In just 10 days of drinking this product, my gut problem dramatically improved. This is really an outstanding, excellent product that I would highly recommend to everyone. Well done RSP, I finally found a protein and a meal replacement that genuinely works and deliver excellent results!

This is my go-to protein powder, and I love it! Great flavor, great texture, and I'm a fan of how there are no artificial sweeteners! I highly recommend using milk instead of tastes so much better.

Ultimate brand of grass-fed whey protein, healthy bios, and natural sugars . This was the combo I was looking for and RSP made it happen for me.

Even though the protein is great, but it is a shame they raised the price by $10. They got you hooked then do this.

I have tried so many different kinds of protein shakes and this is truly the first one that my tummy can tolerate. No digestive issues. Great flavor (chocolate) too!

Clean protein powder tastes good mixes well with water or milk. Tastes just as good with water. Love the added fruit veggie blend! Not buying any other powders again. I like the vanilla better than the chocolate personally (and I love chocolate)

Best-tasting brand of grass-fed whey protein, healthy gut bios, and natural sugars which won’t spike one’s blood sugar level. This was the combo I was looking for and RSP made it happen for me.
