You asked for it and HighT® listened.

Some competitive athletes have a problem with caffeine. They want to feel the fine tuned responses from months and years of training. During the heat of the battle being ‘in control’ can make or break you. The difference between too much adrenaline and not enough. Now with an increase in Nitric Oxide to expand even more blood flow to your muscles, the HighT® Decaffeinated formula is here.

What is important to YOU is important to HighT®.
We ARE ready – are YOU!


In a man’s brain, there is a complex chain of signals called the hypothalamic-pituitary-gonandal axis. The Testosterone produced in the testes is regulated by this chain. At the onset of puberty, there is a rapid increase in the product of Testosterone. But just as rapidly as it increases at puberty, Testosterone production begins to slow from the age of 30 onward. HighT® has been scientifically formulated to help Testosterone levels, leading to increased sexual libido, muscle mass and energy levels. This advanced Hard Core Formulation includes NO3X® Nitric Oxide Booster and Raspberry Ketones to improve endurance, speed recovery time, and maximize strength before, during, and after a workout.**
