Powerlifter Thomas Jamael of Canada has been banned for four years after testing positive for 11 unauthorised substances.
The Canadian Broadcasting Corporation reports that Jamael's urine sample was tested during competition on February 11.
It revealed the presence of anabolic steroids nandrolone, testosterone, methandienone, oxandrolone, oxymetholone, clostebol, boldenone and drostanolone.
Also found were tamoxifen and letrozole, which are hormone and metabolic modulators, along with cannabis.
Jamael is not allowed to participate in any capacity in any sport that has adopted the Canadian Anti-Doping Program (CADP) regulations until April 19, 2021.
This includes training with his team-mates.
Jamael is the latest in a long line of powerlifters to fail doping tests in recent times.
Earlier this week it was announced by the International Paralympic Committee (IPC) that Russia's Sergei Sychev has been suspended for two years for committing his second anti-doping rule violation.
Sychev returned an adverse analytical finding for metandienone in a urine sample provided on June 21, 2016 in an out-of-competition test.
This substance is included on the World Anti-Doping Agency (WADA) 2016 Prohibited List under the category S1.1A Exogenous Anabolic Androgenic Steroids and is prohibited at all times, both in and out of competition.
Sychev, a two-time European champion and 2014 world silver medallist in the up to 72 kilograms class, will be ineligible from competition for two years from July 29, 2016, the date of the provisional suspension, until July 28, 2018.
In September of last year, during the Rio 2016 Paralympic Games, Kenya's Gabriel Magu Wanjiku received a reprimand after taking cough medicine that contained a prohibited substance.
