from my understanding you have to be taller but also have your organs and glands proportionally bigger, those people in modern times and over the last 200 years or so who had health issues, they apparently had too much hgh and the organs/glands and brain weren't proportionally bigger alongside the height. This type of unhealthy tallness is probably more common than it's ever been in the past with PUFA and all the modern environment issues. you can still get some level of height and other growth with estrogen and without androgensHighly doubt it being possible. Think about how even the tallest people in the world, over 215cm let's say, experience a host of health problems. It is inconceivable for humans several times taller than this could have existed.
