Welcome Mash.
Great intro, and you found the right place. This forum is unequaled in this arena.
I can highly recommend Defy Medical.
Do a search on this forum and you'll read a lot of info on how they operate, i've recommended them several times.
A lot of us started with trt and then took it from there. When I started trt with defy I was 127. Talk about feeling like sh1t.
The first step is to get with a Dr. (Dr saya at defy is my recommendation, theres several to choose from) and get yourself started. They'll typically recommend 150 - 200 mg/week.
Once you get started then sit back here and learn all you can, its a learning process. Ive been at this 3 years now and i've finally got it pretty much nailed down, the trickiest part (for me) is controlling E2.
Good luck man and ask any questions, there's no stupid questions this place is a brotherhood and everyone is willing to help.
