I need some biofags here. Let's say I wanted to make mice that produce HGH so i can harvest them like a Jew harvesting adrenochrome from little white children. I found a study pertraining to this and wondering if this is a feasible, cheap idea and a better solution than harvesting human pituitary glands.
