I purchased the Ultragen RS-Recovery cappuccino flavor by first endurance and do not like the way it mixes. The product works well but I will not purchase it next time due to the foam head that forms every time I mix it. If I use a blender bottle it is almost all foam. If I just use a spoon and mix it in a glass its better but still not acceptable. To much product lost in the foam you cant drink. Not wanting a refund, just passing on my experience.
