Use it regularly and you will be impressed. But obviously, it depends on your training since it's a high powered food. The more it has to do (repair and build muscle) the better the results. And it will do so better than anything else on the market.
I like tropical orange with Splenda. For a totally decandant drink I add sunny delite. Yeah, I know, that's a ton of sugar carbs but it tastes freakin awesome. I also like the chocolate with stevia but I add extra cocoa to it and mix it with whole milk. Tastes amazing.
