Keystones in my Coffee!

If you are here, you already know the benefits of collagen to the body. So I'll just say it goes GREAT in my coffee every morning after a workout. Fast shipment, rewards system, and loyalty discounts. Nuff said!

Very good

I put it in my coffee to get a little protein and I enjoy the benefits. There is no taste which is what I was hoping for.
