Before becoming a bodybuilder, Shavershian had been described as a "skinny kid"[7][10] and an ectomorph.[21] Once he completed secondary school,[15] inspired by his bodybuilder brother, he joined a local gym and began learning about nutrition and training, applying it to his pursuit of becoming a bodybuilder. He would spend three to four hours a day training in the gym.[21][22] His favourite professional bodybuilders included Arnold Schwarzenegger and Frank Zane.[21]

In an interview with bodybuilding website, Simplyshredded.com, Shavershian recalled that he originally wanted to become a bodybuilder to "impress girls". He said he would look at pictures of "shredded" bodybuilders and tell himself that he would one day be like them. Almost four years into training, he stated that:

“ I can safely say that my motivation to train goes far beyond that of merely impressing people, it is derived from the feeling of having set goals and achieving them and outdoing myself in the gym. I absolutely love it, the feeling of pushing out that last rep, and getting skin tearing pumps is something I don't see myself without.[21] ”

Prior to his death, Shavershian was the poster boy of a subculture of amateur bodybuilding in Australia, dubbed "aesthetics",[23] which he had made popular.[22] He had established his own protein label, Protein of the Gods, released in June 2011.[9] He also had a clothing line,[24] and Zyzz's Bodybuilding Bible was released on 17 May 2011, based on a compilation of bodybuilding knowledge he had acquired over his four years of training.[7][25] He asserted that the internet helped build up his brand, and it was ultimately made possible through the use of social media.[26]

On 14 July 2011, Shavershian's brother Said was arrested for possession of anabolic steroids,[12] to which he pleaded guilty after Shavershian's death.[3][27] The Sydney Morning Herald covered the case, and included a photo of Shavershian.[12] He objected to the use of his picture to illustrate what was essentially an article on the misuse of anabolic steroids.[7]

When asked by The Daily Telegraph, Shavershian denied ever using steroids, and claimed that his body shape was due to hard work in the gym and a strict diet.[25] According to The Sydney Morning Herald, the company which employed Shavershian as a stripper maintained that he was "a lovely guy, aside from the steroids".[28] Shavershian often used phrases such as "riding bicycles", which, according to The Daily Telegraph, is "gym slang for using a cycle of steroids".[16]
