The lower the bodyfat, the more vascular you will get.
Eq brings out some sick veins. You will get new veins and the existing main veins will get a lot bigger and pumped. It was the first time I got veins that went up my abs. And the vascularity is pretty much permanent (of course not as pumped off-cycle but the new veins stay and I still look juiced when I get a pump in the gym even though I'm off cycle).
Love me some EQ.
