Best Price for a Quality Product
I’ve been drinking protein shakes daily for years. Usually I was using pre-mixed ones but decided to try these as a recommendation by my coach/ CPT. At first I wasn’t too crazy but after about 3 or 4 days I was sold. Now it’s been a couple months and I’m hooked. I got the vanilla and it’s perfect to mix with other flavors/ blend in fruit!

Another happy purchase from Rivalus
Love this stuff. I think this is my 4th different flavor and aside from being a little underwhelmed on the chocolate, I’ve loved everything I’ve tried from rivalus. This stuff mixes really well and has a very pleasant flavor. I’ve really enjoyed mixing this with juices. I’ve got some minor lactose intolerance issues so depending what I’ve had during the day, I’ll use juice. Mixing this stuff with pineapple juice is pretty amazing, it’s like a pina colada. Would highly recommend, will be buying again.

Taste good and dissolves well.
My husband adds this with PB powder and almond milk for his shakes. Says it is the best tasting he has tried .

Best protein
This protein is multi-sourced which means it is utilized in a time release manner. Each type of protein is absorbed by your body at different rates. Some immediately, some over longer periods of time. Tastes wonderful. The vanilla smells like cake mix. You'll be tempted to eat it out of the container. Best protein I have ever used.
