Does beer really help to improve muscles? I have heard from many people that beer helps to improve muscles.  Generally one way to improve muscle is by exercise (maybe dance, gym, games).  As far as I know, beer (alcohol) is a diuretic, which makes kidney produce more urine, so drinking beer too much can lead to dehydration.  So the combination of beer and exercise (sweating) would lead to a worse condition. 

So my question's are:


Does it really help to improve muscle?
If it does, then how?  And when should it can be taken?  Before or after exercise?
There was a study at the University of Tokushima that showed beer containing flavaprenin 
(8-Prenylnaringenin), which is found in hops, limited muscle atrophy in debilitated lab mice. The idea that humans could have benefits of flavaprenin through drinking beer is not quite right, as you would die from alcohol poisoning before you would see the benefits.
