text: has anyone tried lipo-6 by nutrex? how does it work ?is it a thermogenic a lipotropic or both? does it make you alert like ripped fule and other preworkout pills? lipo 6 is a thermogenic fat burner.  it probably does make you alert.  it's got caffeine and yohimbe hcl (increase bloodflow).  although i hear it works pretty well, i've also heard some bad stuff about it...namely that it raises blood pressure.  also, guggulsterones (another ingredient in it) look to be harmful to both gains and even slightly to health (by blocking the receptor that produces testosterone and activating the progesterone receptor).    try scorch v3.  i've never had to use a fat burner but this one seems to be popular and doesn't have the guggulsterones in it.
