India shot-putter Navin Chikara on Friday was banned for four years by the integrity unit of the global athletic body for failing an out-of-competition dope test back in 2018. Chikara was found guilty of using GRHP-6, a prohibited substance, and his ban, which has been backtracked to two years, will end July 27, 2022.

“On 27 July 2018, the Athlete was subject to out-of-competition Testing pursuant to the Testing Authority of the National Anti-Doping Agency of India in Patiala,” AIU said in a statement. “On 28 October 2018, the World Anti-Doping Agency accredited laboratory in Montreal, Canada, reported an Adverse Analytical Finding for the presence of GHRP-6 in the Sample.”

Chikara had won a silver medal in the Federations Cup in 2018, and it was the same year when he emerged runner-up in an Inter-State Championship. In November that year, the ban was imposed on the 23-year-old and the AIU was informed a month later that the athlete had accepted the ban and that he was unaware that GRPH-6 was a prohibited substance.

On March 12, Chikara admitted to the “Anti-Doping Rule Violations and accepted the consequences proposed by the AIU (including a period of ineligibility of four years) by returning a signed Admission of Anti-Doping Rule Violation and Acceptance of Sanction Form.”
