Well, I don't know if it'll help, but I worked with a trainer who was a power lifter and also competed in body-building comps.
He recommended a recovery drink as soon after a hard workout as possible. Key ingredients were things muscles need to repair after a hard workout--something sugary and 40 grams of whey protein. I buy the stuff at the store an mix my own using orange juice for the sugar and any kind of whey protein that doesn't have flavoring.
The only supplement I use is creatine after my work outs. I do feel it helped recover and improved gains.
