I just picked up a bottle at VS for 27.99. The dude working there asked if I like Jack3d, I told him I love it. He told me he hated the sample he tried. Said he felt no strength increase and was up until 2:30 am after dosing at 1:30 PM. He swears there is Niacin in it because he got the tingles that lasted hours according to him. I laughed at him and told him it was the BA, but he swore he'd taken BA before and never got tingles. I also told him there was no niacin in there at all. He was kind of a tool.
