BSN®'s original weight management formula was developed to increase the burning of fat and calories while keeping energy levels at a maximum. Along with the positive fat burning effects, THERMONEX™'s proprietary blend of caffeines, thermogenics and tyrosines is designed to improve physical performance, promote mental alertness and acuity and regulate thyroid function already in a normal range.

An extremely sought after benefit is the absence of a post-serving crash; this is made possible with Naringin, prolonging the effects of all other ingredients, steadily bringing energy up, leveling it off and then slowly bringing energy levels back down.
