These Nut Stacks...REAL OR FAKE

i wouldnt say pumoing because the way pumping wors is that it draws blood into the area, and the amount of blood that would take probably would make him pass out, and possibly kill him. more realistic options are saline infusion or silicon implant, if i had to guess i would say the latter
 
He's real and lives in Minnesota, goes by the name of GReg.
Has been injecting himself with silicone for many years now.

He's an occasional poster on one of my yahoo groups.
