Where and how big your veins are are determined mainly by inheritance, followed by training and leaness/sub-q water. One of the biggest non-genetic factors determining veiny-ness is AAS. These directly contribute to vascularization, which is one of the reasons that men are more veiny than women, and juicers get outrageous veins protruding (men AND women). I have good veins for phlebotomy, but don't have ANY that protrude. Presumably a few good cycles would sort that out if I wanted big veins.........
Now that's some veins... Gotta git me some of them, LOL
