I was never real veiny. But the rope veins in my biceps didnt take long to become visible. Always had alot of veins in the forearms too. The leaner I am the more theyll come out. The two arteries in my biceps are always visible. When my chest and shoulders get pumped, theres a vein that runs from my shoulder across my chest too. My traps are real veiny when they contract with heavy weight, or if I flex them holding my breath.
