Initially, when consuming high levels of creatine for the first 5 days, it is likely you will gain weight through water retention, approximately 1-2kg at most. It is not uncommon for individuals to maintain the water weight whilst continuing to supplement Creatine, as water is pulled to the muscles. However, once the Creatine cycle stops your weight will likely reduce as the muscle water retention reduces.
If weight gain from water retention is not ideal for your situation, you can skip the loading phase and start directly on the maintenance dose of 3-5g per day. If you chose this method, ensure that you continue supplementation for at least three weeks for optimal benefits.
