Hey mate, I was in the same boat as well a few years ago. I'm 52 now and have been going to the gym for about 10 years but had always been natural. When I wanted to start TRT I had gone to a few different GPs (who want nothing to do with TRT) and I also looked into clinics. I'm from Sydney and I'm sure it would be the same in Victoria where there are only a handful of clinics that would do this and most of them are all done online. I don't remember the costs but they just seemed too expensive. From memory, they wanted consultation fees, fees for the blood tests, fees to go see them each time for a prescription. Just not worth it. So I started doing my TRT myself. I get my blood tests done through my normal GP regularly (through medicare) and just purchase my testosterone myself.
Now I'm cruising on TRT and loving life. I did one cycle mid last year, absolutely amazing. Now I'm looking at doing another one.
Let me tell you, this stuff will change your life!
Bedroom drive... morning woods... you name it!
Good luck with it.
