As someone already responded in another thread you posted.. basically the same question.
No magic pill will do it if you have a high bf %. Once your low... way low, ripped from diet and cardio... try NO2, something along those lines if need be.
As stated before in that other thread, it has alot to do with genetics as well... some people have road maps for veins others not so much.
good luck though.
