what exactly causes increased vascularity?

[smartwater]

what promotes this? low bf%.
in pros is down to genetrics and dieuretics more

[01dragonslayer]

Low BF.

[Swifto]

Genetics, low BF, muscle mass.

[Alex2]

I'd say factor # 1 is low BF (less than 10% in general), # 2 Genetics, #3 is muscle mass.

Wouldn't an increase in RBC widen them a bit and make one appear a little more vascular when on some AAS?

10% bf or less makes them veins start popping out.

bf & vasodialation

[stayinstacked]

I disagree, I think most of it is genetics, then low bf. Some people have killer veins even at 12 or 13%, and some you cant see until the guy is down around 7-8% bf. But the guys who have good vascularity genetically, it all just becomes even more pronounced when they diet.

that is true! i for myself only have some veins on my lower abs and two big ones on each of my biceps... when dieting to a respectable BF% (around 9%).

Other members of my gym always have arms veiny as hell despite the fact that they are fat bastar*ds.. its all genetics.
