How many of you get the niacin flush effect from no products. Ive had it with two so far. Muscletechs nanovapor and now the gnc no maximum loaded. After about the third day this crap had me glowing red and my eyes started swelling. Im assuming it was niacin buildup or maybe just a slight allergic reaction. Skin got really hot and my nuts even itched some. Yes my allergist said thats a reaction sign too. LOL Well for some of you its an std sign.
