Is it possible to make a person grow huge?

Question

I don't mean fat. I mean like giaganitc, like godzilla sized.

Answer 1

Well, godzilla sized, no. But there are people who are huge due to a problem with their body's secretion of growth hormone when they were younger. When you are young and still growing, too much growth hormone can cause you to grow too much.

So, by injecting growth hormone into a person who is still growing, yes. If they have stopped growing, their body's will change, but they won't grow huge.

Answer 2

Mostly NO.

The human body design begins to have real problems

when it gets to seven feet or so tall.

Wiki "square / cube law" to see why.
