Rich Chocolate

Best chocolate flavor for me

Chasen C.
Good product!

Honestly I am more of a chocolate guy when it comes to protein but I got a sample of the Strawberry and it was good! Great tasting with a light feeling. Didn't feel heavy and dense like others. Mixed easily with no clumps. Just bought some other flavors to try! I would recommend

Gregory R.
Strawberry was excellent

Very much enjoyed the taste of this post-workout. Used it with unsweetened almond milk.

Alex H.

The chocolate was a little too much for me but the strawberry and peanut butter sold me!

Rivalus delivers again

Great taste, good after work out protein source.

Good Protein with Great Taste

Was very pleased with this sample. The Rich Chocolate flavour tasted very good. I mixed with water as recommended however I think I used a little too much so it was a little watered down. But I could tell the flavour was excellent. I might try some almond milk next time for a richer taste too. What I liked about this protein is I'm trying to eat low carb and this only contained 3 carbs / serving. So perfect for how I'm eating. I would recommend.

Tasted Great

I didn't think I would enjoy this brand but after I tried it I have to say I enjoyed it.

Love it

So far all the flavors I've tried of this brand are great. They mix well with almond milk in a shaker cup. Would definitely recommend.
