Hey brother,
Lots of good questions here. If you want to start with a light oral only cycle, 8 wks of anavar at 40-50mg ED would work. It would be a mild cycle and you can gain if you are eating right and training. You will still need to do a PCT after this cycle.
Dont worry about MENT at this point. There are a lot of reasons you wont want to inject ED or EOD for your first injectable cycle. If you run a test cyp or test e cycle at 2cc EW, you will do very well. You'll also need to run an AI and do PCT after. You want to see how you resond to test and then from here, any other steroid you add to future stacks, should be stacked with test.
Before you jump into any of this, I think you understand that you need to do a lot more reading and research. I'd suggest you go to juicedmuscle.com and check out the forum. There is lots of good info posted in the steroid beginners section, including a good write up about how to do safe injections.
