The 31-year-old, who competes in the men's T54 class, returned an adverse analytical finding for boldenone in an out-of-competition urine sample provided on December 7 2020.

The substance is a banned anabolic androgenic steroid, known to increase muscle mass and strength.

Gharbi will be ineligible to compete from February 5 2021 to February 4 2024.

Any results that Gharbi achieved after the date that the sample was provided will be disqualified.

He will also have to forfeit any medals, points and prizes achieved after December 7 2020.

Gharbi won a bronze medal at the Rio 2016 Paralympic Games in the men's T54 400 metres.

Gharbi also won two gold medals at the London 2017 World Para Athletics Championships in the 200m and 400m, as well as silver in the 1500m and bronze in the 800m.

Several athletes have been banned for taking boldenone in the past, with Jenrry Mejía one of the most notable examples.

The Dominican baseball pitcher was suspended in July 2015 when he tested positive for the drug, and in February 2016 he again tested positive for boldenone.

This marked his third positive test for a performance-enhancing drug, for which he received the first drugs-related lifetime ban in Major League Baseball history.

Three Colombian weightlifters tested positive for boldenone during the qualifying process for the Tokyo 2020 Olympics, and claimed to have ingested the substance through tainted meat.
