"There is a time limit for when HGH is no longer effective, and it is not at the point of growth plate closure, but some time after it.
Why would I claim this idea? Well, the body of a 30 year old and a 23 year old is very different. I suspect that even at the age of say 24 or 25, even after the growth plates are supposedly “closed” a person who gets a high enough HGH stimulation would find that they would be able to increase their height, but only by as much as 1-1.5 inch though."
f the person is young enough, a high enough HGH injection into the body would shock the body into vertical growth for the last time.
It would stimulate the following areas of the body to grow…
The fibrocartilage in the region of the IVDs would differentiate into hyaline cartilage.
The 2 very thin layers of hyaline cartilage sandwiched between the discs and the vertebrate bone will start to proliferate just a little.
The irregular shaped bones in the feet will grow periosteally, have the macroscopic effect of pushing the overall skeletal system upwards, thus grow taller.
The layer of articular cartilage in the hip joint will increase as well, as well as the articular cartilage of the tibia and femur in the knee joint.
