I am 18 now and when I turned 10 I had to take HGH and I stopped about a year ago when my doctor told me I was done growing. I wasn't even on the growth spectrum in my preteen years and I am about 5'6" now. I've recently noticed a few things though. My head is much smaller than anyone I have ever met at my age, I can't wear hats at all and no fitted hats fit me. My torso is really big now since I have been working out and it is extremely noticeable. Do I need to start taking HGH again to continue the progress of my cranial growth? My neck is also small/skinny, it hasn't grown at all over the years. I remember never being able to wear hats the right way but I think my body was always small enough that it didn't seem wrong. Is there any way to make my head and neck grow again?
