Dr. Jonathan V. Wright'sA Dietary SupplementPropel is a nutritional supplement formulation designed by Jonathan Wright, M.D. It contains propionyl-L-carnitine (PLC) and acetyl-L-carnitine (ALC). These compounds are natural derivatives of the amino acid carnitine, which plays an essential role in cellular energy metabolism. They have been found to be beneficial in maintaining healthy sexual function in men, among other aspects of human health. Propel also contains the potent antioxidant lipoic acid (known as the "antioxidant's antioxidant"), both to neutralize the pro-oxidative tendencies of ALC and PLC and for the varied health benefits it provides independently of that role. Propel yourself to new sexual heights. Propel...for the power and excitement of all your lift-offs.
