 Extendivite really works. Here are some reviews from Amazon.com. John Hess, 5 out of 5 stars. Awesome. Probably my only review, but at age 40, I was getting bad heart drop and left arm pain, mainly before bed. I even stopped smoking and drinking sodas for a month, and that didn't work. After one day of taking Extendivite, it was gone and hasn't returned in three years. I've ordered Extendivite 13 times, so Amazon just said.
