What are you cycling OP? Var made my veins go crazy... To the point where I look like a freak doing a reversed grip deadlift (inside forearm veins... I have more veins there than bare tissue!) or oly-bar rows.
Var also allowed my veins to stay post cycle. Which was very nice. I've seen many people get incredibly vascular, only to have them fade after PCT. Likely due to RBC and blood volume, yes... But also due to decreased muscle volume. Large pumped muscles push veins tightly against the epidermis, making them more visible.
