For sure. We have a 17 year old kid in his senior year in highschool that comes to the gym. He’s a wrestler and literally looks like a comic book character. His muscles have muscles.
Not saying it doesn't happen but the eye test standard seems low. 100% this level of muscle can be put on naturally.
There are people who are past this and most definitely enhanced IMO. If I just saw this picture PED's wouldn't even come into my mind.
