Review: Gainz o clock - I would use this in my nightly shake. Easier to hit protein goals for those gainz! Tasted pretty good. I always mixed with water, raspberries, PB and honey maybe.
Review: Best protein powder I've tried. - The taste is great. It doesn't taste grainy. Mixes right up with a shaker bottle. My bariatric doctor recommended them when I had weught loss surgery in 2010. I've been drinking them daily since and I've tried other shakes. I always come back to these. The cookies and cream, and mint cookie is delicious too.

### ⭐⭐⭐⭐⭐ Delicious!
*by S***A on April 22, 2024*

In the past I tried the Nectar series of syntrax and really enjoyed their roadside lemonade and green apple(ecstasy?) so I know they made great tasting products. The peanut butter cookie flavor is phenomenal. It tastes just like a peanut butter cookie, and even has tiny bits of them . It reminds me of dunking a cookie in milk. I've been using it with oat milk, and also mixing it with their bananas and cream on occasion(until I ran out of one or the other), or chocolate flavored oat milk. Sometimes all three!
