Ghazaryan also won the bronze medal at the 1999 Junior World Championships under 56 kg category and the silver medal at the 2000 Junior World Championships under 62 kg category.

He competed for his native country Armenia at the 2004 Summer Olympics in Athens, Greece, finishing in fourth place in the men's featherweight (62 kg) division.

Though Ghazaryan lifted a total of 295 kg, the same as the bronze medalist, he took fourth place due to a personal weight difference.

Ghazaryan later won a bronze medal at the 2006 European Weightlifting Championships.

He still remained close with his friends on the Armenian national weightlifting team.
