Why Us?

Dieting is Tough. Let Viper Ease the Load. Dieting can be horrible. Your mood can dip, your energy levels can plummet, and your drive to exercise can dry up completely. We wanted to create a product that addressed these often-neglected problems which invariably lead to diet failure - something more comprehensive than your average 'me too' fat burning supplement. Viper brings together the best nutrients and amino acids for the job: the energy-boosting benefits of caffeine, glucomannan and L-tyrosine; the thermogenic power of green tea, raspberry ketones and yohimbe; the appetite suppressing ability of L-carnitine, and kola nut. Everything is put in place to work synergistically and deliver big-time energy, big-time fat burning, and big-time results in the mirror.
