[6][7][8] In July 2011, Shavershian gained more media attention when The Sydney Morning Herald published an article about the arrest of his older brother, Said, for illegal possession of anabolic steroids.

[3][15][16] Prior to his death in August 2011, he was set to graduate from the University of Western Sydney, with a degree in business and commerce.

[19]Shavershian was the poster boy of a subculture of amateur bodybuilding in Australia, dubbed "aesthetics",[21] which he had made popular.

[24] On 14 July 2011, Shavershian's brother Said was arrested for possession of anabolic steroids,[9] to which he pleaded guilty after Aziz's death.

[18] When asked by The Daily Telegraph, Shavershian denied ever using steroids, and claimed that his physique was the result of hard work in the gym and a strict diet.

[6][28] His family stated he had shown several minor symptoms in the few months leading up to August 2011, including high blood pressure and occasional shortness of breath.

[32] Said Shavershian created a 19-minute tribute video for his brother, titled Zyzz - The Legacy,[24][33] and released it on YouTube on 22 March 2012.

Shavershian's followers still frequently post tribute videos dedicated to him, with a lot of them collecting over a million views.
