I believe its either nasser or or Ronnie Coleman. Ronnie would have the legal connections he claims to have.
i did consider ronnie as well, but gh15 often refers to arnold as best bodybuilder ever (right above ronnie) whereas ronnie considers lee best ever. I think it's dennis. someone put up a pic of DJ in the gym with the caption "our god of hormona" and gh15 quoted that post with a 'lol'. of course that post has been deleted now.
bigbobs says that nasser hadn't touched a computer at all during his visit, yet gh15 had made new posts throughout the day while they were together - i think nasser can be ruled out.
so it's either DJ, ron or gunther. i can see why gh15 would be so against 'insulina' when you realize that DJ has probably the biggest gut in pro BBing. it ruined his physique completely
