The Best

Excellent tasting protein. Feel great after taking it. Do not hesitate buying from Promix

Glad I Found You

My search for a peanut butter flavored whey brought me to Promix and I'm glad it did. The flavor is outstanding and I look forward to trying more of the Promix line which looks quite impressive.

Delicious PB!

The taste and nutrition is amazing!!! Not sweet and is so satisfying! I add to my oatmeal or just with water

Jon G.
Clean and Good Tasting

I really like the fact that it has few ingredients and still tastes great. I used to use unflavored whey and peanut butter/fruit/etc. to make my own shakes, but got tired of cleaning the blender all the time. This allows me to just stir into a glass and drink. I mix with 12oz of skim milk and it mixes pretty well. My favorite flavors are peanut butter and vanilla.
