Hi guys, need help. I have been thinking about having a go of the gear. I have absolutely no idea where to start.

Info -

I am 33 yrs young
5`8 - 175 lbs
Have a decent spare tyre around the mid section!

I am looking to bulk up at first and would then like to get a bit more definition. Before I start this I am going to do a fair amount of research but I would like some pointers in the right direction.

Also I do not want to inject. That scares the shit out of me. Any guidance would be much appreciated.
