During the investigation, according to the testimony provided by Tyson Gayin:

In May 2012, human growth hormone (hgh) was provided to Tyson Guyon for the first time, and the provider was unknown;

On July 15, 2012 (the eve of the Monaco Diamond League), Tyson Guyon took banned drugs (Gibson's ointment) for the first time;

In November 2012 (after the partnership with Drummond was terminated), Tyson Gayon went to Dr. Clayton Gibson alone and agreed to use the ointment provided by Dr. Gibson.

The doping incident caused quite a stir, but the follow-up ban work has always been in a state of "procrastination".

According to regulations, athletes who use steroids and other growth hormones for the first time will face a two-year ban. However, the energy of various American sports associations is too great, and Tyson Guyon has a good attitude and actively cooperates. Maybe the final ban will be two consecutive periods.

Less than a year old.

Wayne's memory of this incident is very profound, because it was not until May 3, 2014 that the United States Anti-Doping Agency officially announced that Tyson Guyon would be banned for one year (2013.6.23-2014.6.23

), and cancel the results and honors obtained after July 15, 2012, and hand over the London Olympics relay silver medal penalty.

After 10 months of investigation and evidence collection, Tyson Guyon's ban was finally announced, and the time when the ban was announced was less than two months before his ban expired...

In contrast, the process and results of Asafa Powell's drug-banning scandal were obviously different.

In the incident, five Jamaican athletes, including Powell and his female teammate Sherron Simpson, were disqualified due to positive drug tests. When the results were announced, they were still training in Italy with the Jamaican track and field team.

Investigators found the banned ingredient parahydroxyephedrine in the nutritional supplements he and Simpson took daily. Powell and Simpson said the nutritional supplements were provided by their physical trainers and they were unaware that they contained banned ingredients and took doping.

This incident was an "honest mistake".

But their physical trainer, Canadian Shwelebu, said that he has never provided athletes with "other drugs other than commonly used vitamins."

Powell and Simpson admitted during the investigation that they failed to provide a complete diet list to the anti-doping agency before taking the drug test. Powell's explanation for this was that "the tension before the drug test made me forget the names of the drugs."

However, whether it was due to "taking the wrong medicine" or being "too nervous", the three investigators responsible for the case finally agreed that as professional athletes, they should pay the price for their "carelessness", and therefore made a ruling of suspension.

On November 10, the Jamaica Anti-Doping Commission’s decision on Asafa Powell was: an 18-month suspension from June 21, 2013 to December 20, 2014.
