Welcome to the darkside of AAS!
What you're talking about is typically called "cruising and blasting" where TRT is the cruise and a blast is a cycle added on top. Lots of guys do it. I do it. I've done blasts with Tren, Anavar, and Masteron.
Do a search on Tren in this forum and you will find a ton of threads on Tren and its side effects. Tons of other online references too. Bill Roberts is major contributor to at least one other website I'm familiar with and he does a write up of every major steroid, weight-loss, anti-estrogen, and misc. drugs out there. He even gives recommended stacks, and doses.
Sorry but forum rules prevent me from sharing the website, but you can find it with a little research.
