as bodyworks said.. its an expensive cycle and potentially could provide you with very little.

you mention you have probs with energy. id look into getting your diet sorted mate and spending some money on a few choice supplements first and see how you respond to this.

creatine (try extreme nutrition kre-volution) and glutamine may help. also, altho i dont belive in them (as i dont think they directly build muscle) there are quite a few pre-workout nitric oxide supplements about at the moment which will give you an excellent kick up the ass for your training.

in my opinion this approach will give you much better rewards and save you some cash!
