Cephalic vein

Pretty sure it has more to do with body fat. I've seen skinny guys with that vein on the bicep

genetics
volume
low bf%
a good pump
strong biceps
tren

these are all methods of getting vascularity

lose body fat and gain bicep mass dummy

bicep mass

even at quite a high bf%(17%) İ had my bicep vein cause of dem curls BREH

so much of this is just how lean you are. Some people also just seem to be more vascular regardless of bodyfat percentage and muscle mass. I'm not sure if this is due to blood pressure or if their veins are just a little more superficially located.

fuck this vein i want those horizontal spider veins and to look like a road map i got this shit after cutting to 12% and idgaf

Cut and smoke cigs.

>tren

this, I hardly had any vascularity even with fairly low BF, then when I got on tren it was like a highway from my wrists all the way up my shoulder and chest. Probably since it raised my blood pressure

im lean enough to have striations in my arms/delts but i don't have a bicep vein thing showing.

Vascularity is mostly genetic. My bodyfat is about 20% (no visible abs) and I wake up with arms more vascular than that that guy.

Genetics give you bicep veins. Ive had them since I was 8 and skinny fat
