is vascularity in any way related to heamoglobin count?
I seriously doubt it.
more to do with a combination of things..
1- having thin enough skin. be it from bf, or water. even local sub-q water from site injects will blur vascularity.
2- veins that are dialated, not constricted (stimulants constrict)
3- blood pressure
4- hydration. drink enough water that your piss is clear
5- genetics. look at flex wheeler, his vascularity sucks, even in his best condition... johnnie Jackson.... even dorian yates didn't have good vascularity even with his translucent skin.... then look at guys like Paco Bautista and branch warren.
