I am extremely lactose intolerant and have been looking for a protein shake that does not make me sick for a long time. After purchasing this shake, I can gladly say I've found it!
Being extremely lactose intolerant, I often tend to get sick from things that taste like milk, even though the lactose content is minimal. This shake has a strong milk taste, which is the only negative thing about it. But, I decided not to mark it down as all protein shakes have a strong milk taste, and because you can easily go around the milk taste by mixing it with Gatorade powder or crystal light on the go packs (sugar-free). Without mixing it with something else, however, I can't drink it. If you do not like a milk taste, then I'd recommend you get the Strawberry flavor as you can easily mix it with out flavors... not so much with the Chocolate or Vanilla flavor.
The best thing about this shake is that it really doesn't contain any lactose (other's say they contain zero grams, but still contain milligrams), and it does not upset my stomach. I sometimes feel a bit bloated, but it doesn't last very long as the hydro whey is quickly digested.
As far as the results go, I am already starting to see result after just a few days. As far as the preparing goes, you really don't need to blend it, you can simply stir your shake and it'll be fine as well.
My ratings:
Taste: 2/5 (This is obviously subjective, others who love milkshakes will love it)
Mixing: 5/5 (Stirring or blending works fine)
Digestion: 5/5 (Quickly digested, perfect for people with lactose intolerance)
Results: 5/5 (You'll notice results after a few days)
Price: 4/5 (It's a bit more expensive than other shakes, but it's definitely worth the money)
