Anyone know what age HGH is generally recommended for?

I've been noticing lately that I just don’t bounce back the way I used to. I work out regularly and eat pretty well, but the recovery time is getting longer and I’m always a bit sore. It makes me wonder if I'm just getting old, or if there might be something else going on. My doc suggested that my hormone levels might be shifting, and he hinted at HGH as a possible solution, but I'm curious - what's the typical age range when people start considering something like that? Is there even a "typical" age, or is it all based on individual needs??
