its more than that
jay cutler at 3 % bf has zero vasularity
paul dillet at 15% bf has tons of vascularity
Exactly. Old post to respond to, but I am very vascular even when I'm fat. Used to be a skinny 100lb twig and was still vascular. People made fun of me for being skinny and veiny, now those same mother fuckers are asking me what drugs, diets and training methods they can use to attain the level of vascularity I've got. For the most part, you either have it or you don't.
Drugs and diet can bring it out a little more, but only to a certain extent. Jay for example has been seen rocking some veins (look at his 2001 post O pics - insane), but is smoother than a baby's bottom when in insane contest conditioning without a vein in sight.
When I tried EQ it was pretty nuts. RBCs were too high though and didn't feel anything positive. EQ at a low dose may be good for collagen synthesis but aside from that, I think it's a really over rated steroid. Was considering trying vet grade but if shitty UGL quality EQ jacked up my RBCs that much it's probably something I should stay away from. Some guys get a little more vascularity from it but I think it's a little weak and probably wouldn't waste my time with it again. I got some free EQ that I just gave away because I think there are better options out there.
