For those interested, I found my old growth charts the other day. The top one covers my height from ages 3 to 18, and the bottom one is my weight. As you can see, I never had any problems with weight gain, but there is significant improvement in my height from when I started growth hormone aged 9.
The strange and the eagle-eyed among you can see if you can spot where my doctor has helpfully marked on the time I officially started puberty, presumably in case any of us forgot and really needed to know years after the event. Hooray!
