Is Australian judge really convinced that 1 kg of testosterone may be bought for one person’s personal use?

Carlton Alloysius Hayes, a person from Australia, was accused of possession of almost one kg of Testosterone Propionate. He placed order for powder of this product per internet and acquired it from overseas. This person also wanted to buy benzyl benzoate, a chemical which is used in order to prepare solution for injections from powder. When police officers learnt that this man ordered this chemical, they asked him about purpose of purchasing it. Carlton Alloysius Hayes claimed that he planned to get it for a friend. But he added that he couldn’t remember the name of the friend.
Then Hayes himself contacted policemen and asked them to come to his place. When they came, Carlton Alloysius Hayes showed that he possessed 2 bags of white powder. He also admitted that he had ordered benzyl benzoate in order to mix it with the powder and prepare liquid for injections.  
Carlton Alloysius Hayes weighed approximately 156 kg, when he was in the court. He claimed that he couldn’t lose weight, however he trained at the gym. Thus, he used steroids to lose weight and improve appearance. This man affirmed that he hadn’t had any plan to sell steroids. He obtained the testosterone powder for personal application.
A defense attorney for Hayes confirmed that his client had a good reputation. He always worked hardly.
 However he had to be sentenced to prison because he bought steroids from overseas, the judge’s decision was to sentence him to some months of suspended jail. Thus, this person avoided imprisonment.
