Don't start bulking if your body fat is above 15% for men or 8% for women. Beginning a bulk with high body fat means you'll gain too much fat before you can cut again, making the process uncomfortable.
A good rule of thumb is to not start a bulk when you are above 15%. So 50% or lower than that, then you can consider going for a bulk if that's the goal. If you start the bulk higher than 50%, you will not get enough time on this bulking phase before you would be getting too much body fat onto your body where you would just feel not very comfortable with your body composition that you would like to cut. And remember, females, the number I just gave would be 8. On top of those numbers.
