Who told you creatine is good for fat loss? All it will do, is raise ATP levels, hence increasing your energy levels, because ATP is your energy source. So in the best of the cases it might slightly contribute to fat loss by improving your training, but don't expect any real fat loss with it. You should consider other compounds, such as Cardarine GW or SR9009 for that purpose, but they are in a whole different league than creatine.
