ThermoFuel V9's Comprehensive Formula Uses the Most Powerful Ingredients Available!

Advantra Z® (120 mg citrus aurantium yielding 60 mg active synephrine)

Advantra Z® is the only patented and clinically proven thermogenic ingredient for weight loss and physical performance on the market today. Advantra Z® holds U.S. and Canadian patents for stimulating thermogenesis, increasing lipolysis to facilitate the burning of fats for fuel, reducing weight, increasing lean muscle mass, and suppressing appetite. Advantra Z® also improves athletic performance and uptake of amino acids into muscle cells.

Advantra Z® offers many of the metabolic-enhancing effects of ephedrine without the dangerous side effects. Unlike ephedrine, Advantra Z® does not influence alpha-1, alpha-2, beta-1 or beta-2 receptors, which affect blood pressure and heart rate making it a safe and effective tool for weight loss.  Advantra Z® only stimulates beta-3 adrenergic receptors which increase lipolysis in fat tissue and thermogenesis in skeletal muscle.

ThermoFuel V9 contains only the patented Advantra Z® form of synephrine. Each dose contains 120 mg of Advantra Z® standardized to 60 mg of active synephrine, the highest dosage of any product on the market today. Advantra Z® also contains powerful amines: N-methyltyramine, hordenine, octopamine, and tyramine. Click here for more info on Advantra Z®.

Infinergy DiCaffeine Malate and Caffeine Anhydrous (200 mg caffeine total)

Caffeine acts as a thermogenic agent to raise metabolic rate and core body temperature. It works synergistically with Advantra Z®, boosting its effects by preventing phosphodiesterase from destroying the action of thermogenesis. One of the primary reasons caffeine is effective at aiding in weight loss is its metabolic influences. It's a simple formula: the higher your metabolism, the more calories you are burning.

Studies show that caffeine may also have the ability to liberate stored body fats so they can be utilized as fuel. Burning fat as fuel saves muscle glycogen, enhancing physical performance, thereby increasing energy expenditure. Caffeine acts as a central nervous system stimulant that increases the release of adrenaline, fights fatigue and drowsiness, increases alertness, and improves mental focus. Caffeine may also act to suppress appetite and help eliminate cravings.

ThermoFuel V9 uses Infinergy DiCaffeine Malate. This specialized form of caffeine is milder than caffeine anhydrous and has longer-lasting stimulatory effects without the side effect of jitteriness.

Acetyl-L-Carnitine (625 mg)

Carnitine plays an important role in converting stored body fat into energy. Carnitine's primary function is to regulate fat metabolism and transport fatty acids into the mitochondria of cells, where they are oxidized and converted into energy. Studies suggest that athletes may need more carnitine than their body can produce, so supplementing with carnitine can lead to improved exercise capacity and a reduction in stored body fat.

During intense exercise, carnitine may help reduce the respiratory exchange ratio and lactic acid buildup in muscles, leading to increased energy and greater resistance to muscle fatigue. Put simply, carnitine helps your body burn its own stored fat as energy, leading to increased endurance,  work output and exercise capacity. Studies show that it may even preserve muscle glycogen during exercise, keeping you energized even longer.

ThermoFuel V9 contains acetyl-L-carnitine, which is a stabilized and more bioavailable form of the amino acid L-carnitine. The addition of the acetyl group to the L-carnitine molecule allows it to easily pass through the blood-brain barrier, where it plays an important role in protecting and supporting brain function. Acetyl-L-carnitine is involved in aspects of neuronal metabolism because its molecular structure resembles the neurotransmitter acetylcholine. Supplementing with acetyl-L-carnitine may improve acetylcholine production and stimulation of protein and membrane phospholipid synthesis.

Green Tea Leaf Extract (with EGCG) (500 mg)

Green tea leaf extract is a natural analogue for caffeine that possesses high quantities of catechins, which influence metabolism and fat loss by decreasing fat absorption, increasing fat excretion, suppressing appetite, and inhibiting intestinal lipases, along with several other functions. The most important of these catechins for increasing thermogenesis is epigallocatechin gallate, also known as EGCG. EGCG can help maintain a higher metabolism by keeping norepinephrine, the neurotransmitter responsible for regulating metabolism, at peak levels. EGCG may also increase the level of antioxidants in the body to neutralize free radicals before they cause cell damage.

Theobromine (50 mg)

Theobromine (3,7-dimethylxanthine, or 3,7-Dihydro-3,7-dimethyl-1H-purine-2,6-dione) is a methylxanthine, which is a chemical relative of caffeine. Unlike caffeine, this alkaloid has three methyl groups as opposed to two, which slows the clearance of theobromine from the body, so its effects last longer and do not produce withdrawal symptoms. Theobromine is a mild stimulant that works in conjunction with Infinergy DiCaffeine Malate to give a smoother, longer-lasting synergistic effect.

Cayenne Pepper (50 mg)

Cayenne pepper is added for its ability to enhance metabolic rate. Studies suggest that chemical compounds in cayenne have the ability to increase the body's heat production, thus increasing the rate of metabolism of fats and carbohydrates. Additional research also indicates that cayenne increases the production of epinephrine and norepinephrine, which together decrease appetite. For dieters, it has been suggested that adding cayenne to a day's diet reduces hunger after meals and reduces calories consumed during subsequent meals.

L-Tyrosine HPLC (500 mg)

Supplementing with the amino acid L-tyrosine may be an effective way to safely boost the metabolism for overweight and obese individuals. Tyrosine has been shown to influence the production of thyroid hormone levels, specifically thyroxin, a hormone that regulates the body's metabolic rate. Tyrosine is also an important amino acid for the production of neurotransmitters dopamine, epinephrine, and norepinephrine, all of which have been shown to successfully suppress appetite and increase focus and mental energy. Diet and exercise cause increased stress on the body, which hampers its ability to synthesize tyrosine from the amino acid phenylalanine. Supplementing with L-tyrosine ensures high levels of tyrosine during these stressful times so hormones and neurotransmitter levels stay regulated.
