First of all make sure your at least 23 y/o, 25 is better. If your not at least in your mid 20's you really don't want to mess with your body right now, and honestly if you can't make gains in your late teens and your low 20's AAS is NOT going to fix anything. In fact, it will do the opposite, you will make some gains and continue your bad habits while NEVER learning and fixing what the root of the problem is (99% of the time its diet, maybe 98%

).
Anyhow if you are 25 or older, I suggest starting @ 500mg for 12-16 weeks. I say 500 because most test is 250mg/ml so its just easier pinning 1ml of test E or C twice a week. DO NOT START @ 250mg a week. That will only shut you down and its pretty much a testosterone replacement therapy (TRT) dose ( close to natural level) anyhow.
I would run a-dex for an Aromatase inhibitor (AI) @ .5mg EoD... keep in mind you may have to up it or down it depending on your sides. When the cycle is over, if you feel adex did not do the job try aromasin next time around. <<<< This is a very good example why your 1st cycle is test only. If you stacked many things, they could add or subtract water and give ADDITIONAL sides and you won't know which compound is causing what. Test and your Aromatase inhibitor (AI) is the bread and butter of cycling.
PCT in my opinion should be clomid @ 50mg ED for 4 weeks. Some people will add nolvadex to pct @ 40mg ED for 2 weeks, followed by 20mg ED for 2 more weeks ( 4 weeks total 40/40/20/20).
So these are my thoughts on your 1st cycle, hope this helped out!
