MISSOULA, MT (October 11, 2005) – Technical Sourcing International, Inc. (TSI) announced today that PEAK ATP™, a proprietary nutraceutical ingredient that delivers the exact molecule the human body needs to create energy, is a lead ingredient in a new body-building supplement developed by Sylvester Stallone’s nutritional company Instone™. The new product, Pre-Workout Intensity, is targeted toward athletes who want to be able to train harder, maximize muscle growth and repetitions, and maintain sharp mental focus.

A large volume of scientific, pre-clinical and human clinical data demonstrates the benefits of ATP administration. It has a dramatic effect on circulation without adversely affecting heart rate or blood pressure. At least two different studies have shown that ATP administration produces the same increase in human skeletal muscle blood flow while resting as that seen in exercising muscles. Because of the enhanced circulation, increased amounts of oxygen and glucose are delivered where needed to the exercising muscles, allowing them to keep working. Therefore, PEAK ATP may help weight lifters achieve more intense pumps, benefiting muscular growth and strength. In fact, a randomized, double-blind, placebo-controlled trial at the Cooper Institute Centers for Integrated Health Research found that the with-in group total lifting volume of male bodybuilders aged 18-45 increased by 1,552 pounds – a 28.2% gain – after taking 225 mg of PEAK ATP for 14 days.

Enhanced blood flow provides another benefit to bodybuilders: it helps remove waste products such as lactic acid and ammonia from the muscles, thereby speeding recovery and allowing weight lifters to train faster. Additionally, by enhancing cerebral blood flow, PEAK ATP boosts mental acuity and may lessen the perception of fatigue and/or exercise-associated pain.

PEAK ATP is part of Pre-Workout Intensity’s “ATP Enhancing Blend”; the supplement also contains a “Workout Primer Blend” with branched chain amino acids and a “Mind-Muscle Blend” with well-established mental boosters such as vinpocetine and huperzine A. The product is available through the company’s website, www.instonenutrition.com and is distributed through GNC retail outlets nationwide.
