Considering what you have said, I would recommend you these vital supplements:

- Whey protein
- Casein protein
- Creatine
- Maltodextrin

Combine these except for Casein protein (slow protein) in one big shake, and drink it directly after working out. This will allow for instant muscle recovery in combination with increased effectivity of the creatine uptake (use water). The fast carbs will do it's job to provide your body with energy, while the protein feeds your muscles!

Just before going to bed, have a shake of Casein protein (fast protein), to provide your body with food throughout the majority of the time you are asleep.

Good luck
