Hey,

Vascularity is characterised by a large number of conspicuous, visible, and often extensively ramified superficial veins.

If we consider it on a general note, vascularity is not considered as such bad in physical standards. You have not mentioned the selection criteria under which you are asking about the medical standards.

See, vascularity is not a malfunction. So, as it does not pose any uncomfort for performing any action, it should not be a problem because it is just gain of muscles and nothing else. You need not to worry about the same.
