Actually, it depends on your own training. In order to gain muscle, you must have an adaptation period of one month. Don't practice in different parts during the period, just train all muscle groups every time, three times a week. After a month, practice 5 times a week and practice in different parts. If protein powder and diet are in place, you will see a significant increase in dimensions from one month to three months, but fat will also increase, so that you can lose fat after training for one year, and then you can train step by step.
