About Banned Drug taken by Asafa Powell

The banned drug is named oxilofrine and is a stimulant used to boost the body's ability to burn fat. It helps athletes to boost their power-to-weight ratio with more lean muscle and less fat, and so increase their speed.

It may also increase the rate at which the heart reaches its maximum performance during exercise, meaning a greater supply of oxygen can get to the muscles earlier.

Oxilofrine is an agent that stimulates part of the nervous system and was previously used to treat low blood pressure. More recently, oxilofrine is found in combination with caffeine in dietary supplements marketed as weight loss products.
