How old were you when you first used HGH?

[LightHammer]

18-21
22-26
27-31
31-and up

I probably would have made the cut-off points a bit different, like:

<21
22-25
26-29
30-34
35+

My reasoning is based on the various ages indicated in GH literature and studies and info on this site. Such as age 35 tends to be the age where natureal GH production begins to decrease... etc, etc.
