I also remember one time in college reading how niacin brings your veins out, so I went and bought some at GNC and took like 10x the recommended dosage before class. I figured the girls would wet their panties once they saw me with Ronnie Coleman-esque veins sticking out everything. Anyway, about 30 minutes into class I started feeling really hot and itchy. I looked at my skin and it was like beet red. I almost felt like I was going to have a heart attack...of course I didn't see any improvement in my vascularity. Luckily, it eventually wore off but I remember someone asking me after class if I was ok....probably bc my face was so red. Needless to say, I didn't end up getting the attention from the ladies that I was expecting.
