Best protein!

I love everything about this protein- meet your protein goals & curb your sweet tooth. Vanilla crème is the most delicious flavor that can be mixed with anything or enjoyed alone!

This was my first order, and I received the wrong shipment. I emailed customer service and they responded back in an extremely timely manner (so appreciated!) and made it right.

I would definitely recommend solely based on my experience with customer service. Will provide product update once I try it out! 🫶🏼
