Most people in the bodybuilding industry use the term “bulk” as one to describe a period of caloric surplus to put on extra muscle mass. The inevitable side effect is also gaining fat. So your question is a bit confusing. I think you’re just asking if women can put on a lot of muscle without losing their breast tissue. Yes that’s possible. But, if you’re not lean it’s hard to see the muscle and if she starts taking anabolic, that will likely adversely effect her ability to maintain breast tissue.
Charlotte chant has decent sized natural boobs I think. Not huge, but they’re still there.
Is it possible for the ladies to maintain their natural size breast as they bulk up? or is it inevitable that they lose them?
