No insulin, on none of the photos.
First photo 2003 (age 20) 170 lbs, second 2004 (age 21) 180 lbs, third 2008 (age 24) 190 lbs... But I have used insulin in 2007 and early 2008. I think it would be OK before shows to make the muscles rounder, fuller...but honestly it's all illusion...fake muscle.
First my HGH should have been higher and the AAS...but it never happened...especially not now. I'm working to pay bills not to buy vials.
