The next big trend in doping will be gene doping...the implantation of genes to develop strength, endurance, coordination, or stamina. If this process isn't already on the steroid black market, it appears to be a major future challenge, as the technique is undetectable. Or thought to be undetectable; a German lab says it developed a process to detect gene doping. From Deutche World:
The test traces a special substance, known as GW1516, which artificially increases the volume of so-called endurance muscles and enzymes that gain energy from fat.
"For the first time, a substance for gene doping has been traced through mass spectrometry," the German Sports University Cologne (DSHS) said of the procedure, which was announced this week.
Mario Thevis, a researcher who helped develop the test, said it was ready for use.
