I just went to the 2006 npc midwest muscle classic. It was a good show and I new alot of the guys on stage. I talked to alot of them and not a single one used niacin. I was shocked, I thought that 100mg of niacin half hour before you go on the stage realy brings out vascularity. I also thought that it was something that all bodybuilders do to help them look more shreeded before they go on stage. Whats the deal? any body had any exsperice with Niacin?
