Tetrahydrogestrinone, a previously unidentifiable designer steroid, has now been identified by researchers from the UCLA Olympic Analytical Laboratory in Los Angeles.

THG (Tetrahydrogestrinone) was identified after a spent syringe was anonymously provided to the United States Anti-Doping Agency (USADA).

From News-Medical.Net:

Urine samples were purposely spiked with the newly identified THG and various analyses carried out to determine how the substance could be detected. Although it is not detectable by standard doping control screening, THG was found to be easily detectable by alternate methods. Once detection methods were established, the substance was administered to a baboon both intravenously and intramuscularly, and its excreted urine collected for analysis.

The designer drug identified in this study is different from anabolic steroids previously found in athletes‘ urine samples. The Food and Drug Administration has warned that its use could pose health risks, and it cannot be legally marketed without approval.

Don Catlin, lead researcher, soon started working on cracking the chemical formula of this designer steroid found in the syringe and was able to detect this anabolic steroid. It was found that THG can be detected in urine after IV and IM administration (both).

The FDA has warned all about serious health aftereffects from the usage of this designer steroid and has said that it cannot be legally marketed without its approval.
