Best to drink protein shakes after work out?

Whey protein is just there so you can get some extra protein in your diet, it doesn't really matter what time you drink it as long as you get the right amount of protein every day.

Whey protein has some good branch chain amino acids, so I guess if you drink it before and after your workout, you'll get some more protein synthesis happening. But, you could just buy some isolated branch chain amino acids for that.

It doesn't taste like crap and it has most of what the health food shakes have

It's a good recovery drink

You can't buy muscles, but lots of people will sell you baloney.

Drink water.
