At about what bf percentage do veins on the abs (lower) start to show up? I noticed this morning that mine are starting show up! My bathroom scale has me at 17.7% bf but I am beginning to suspect it is lower than that. Also, vascularity on my shoulders is becoming prominent and even starting to get some action in on the legs.
I am supplementing with L-Citulline (now Citrulline Malate), Beta Alanine and take a 2.5mg cialis daily. These sups no doubt help in vascularity but to what extent I do not know.
