Review: Good taste dissolves well good bang for buck bad Ziploc - Good taste and good portion sizing good bang for your buck as you get a lot of protein for the money. The taste is a little strong at some times. It does dissolve very well in milk or water. The seal isn’t very good so I would prefer to just use a clip instead of using the reusable Ziploc as it’s not very good. Review: Nice powder - Nice product, easy to mix and drink.
