The Athletics Integrity Unit has announced 18-year-old Issam Asinga has been provisionally suspended for the presence/use of a Prohibited Substance (GW1516).

Here’s what you need to know:

– Asinga was preparing to represent Suriname at the World Athletics Championships in Budapest.

— The high school star from Montverde Academy in Florida is coming off a 9.89-second victory at the South American Outdoor Championships in Sao Paulo, Brazil, to set a new U20 world record. He is the youngest person to break 10 seconds for the 100m.

– Many considered Asinga a potential medal threat in the 100m since his personal best ties him for the fourth-fastest in the world this year.

– He also ran a 200m personal best of 19.97 earlier in the season. He is the 15th-fastest man in the world for 200m this year.

– GW1516 is a banned substance that modifies how a body metabolizes fat. Botswana’s Nijel Amos, the 2012 Olympic silver medalist in the 800m who trained with Oregon Track Club, was also suspended for a positive test for GW1516 ahead of last year’s world championships in Eugene.

– Asinga is committed to run for Texas A&M next season.

What he said:

Issam Asinga via Instagram: "As you may have read, the AIU has charged me and provisionally suspended me for an alleged anti-doping violation related to a urine sample I provided out of competition at my home on July 18th.

During the high school season, I agreed to be a part of the registered testing pool, as I recognized I was having a historic season. I have been tested before, and after this alleged offense. On June 10th I ran 10.02 wind legal, and a wind aided 9.83. The AIU tested me at home the next day, and that result is negative. I then competed at a World Athletics Gold Level meet 2 weeks later in New York (June 24). The sample in question is July 18th. I was tested a week later at the South American Championships (July 28th), where I set a world U20 record.

With the AIU’s assistance, the Rio laboratory in Brazil expedited an analysis of my sample which also came back negative last night (August 10th). To clarify, the alleged amount found in my urine sample, is 0.2 nanograms per ml (0.0000002mg/ml). For context, a single grain of salt is approximately 58,500 nanograms (0.0585mg). All my supplements are NSF and BSCG batch tested for WADA banned substances. I respect the AIU’s processes, and I will continue to comply, as we work to find out what has happened.

My team and I are aware that the next generation of track stars is looking up to me, and I would never intentionally let them down. The AIU has agreed to test my B sample, before the world championships next week. Until that time, I will remain steadfast and wait.”
