180g of protein is for your reported weight of around 60kg, some 3g protein/kg bodyweight. A third of that is just going to be pooed out. The

It's like when I stand next to Ricky Ponting and we both throw a cricket ball. I am almost certainly stronger than him, but his ball will go further because he knows how to
apply his strength to throwing it, and I don't. Likewise with weights; for the first few months you may have the strength but are still learning to apply it. So how much energy you have isn't really an issue, and buying and consuming creatine won't help you much.
