Yes I bought some Animal Pump but it made one of my teeth hurt so I quit (BTW, has anyone ever had a problem with tooth pain from supplements?). Anyways I had 2 cans so I gave some out to 3 friends who exercise with me, they all liked it. In fact one friend who rides with me Saturday mornings found he could ride almost 2x as far and felt like he had wings well into the night. He called me on the way to a night spot and was still raging like an Animal (no pun intended) 5 hours later, hehe.
