Using a blend of glucomannan, green tea, synephrine, 5-HTP, hoodia, yohimbine, and bioperine, Zapputight claimed to be a thermogenic fat burner. And they claimed that it could produce this amazing thermogenic effect without any side effects such as jitters. However, Zapputight has disappeared off the market, and apparently is not available through any online retailer at the current moment. We suspect it has been discontinued, which is good considering all the actual possible side effects including heart attack and stroke. Should you manage to find Zapputight selling again, we caution you not to buy this product.
