If you're afraid, step back and do more reading. You can over come a lot of fears by being prepared and having knowledge about gear and how to use it. Yes, AAS are powerful medications and can cause side effects, but these sides can be largely negated with plannining and an understanding of how the drugs work. 

First of all, your plan is good, using test only. Using one compound will minimize risk of sides, and if you do get side effects, you'll know exactly which compound is causing the problem. If you were to use 3 different compounds in this cycle, it would be a lot harder to pin point what the problem was. Another factor is DOSE. Side effects are largely going to occour due to dose. Keep the dose moderate, and you'll be less likely to experience problems. Plus, if you do, they will be a lot easier to manage. The main issue that can arrise with test, is due to the conversion to estrogen.  Test and estrogen are a ying and yang. Using test successfully is about finding the balance bettween these 2 hormones. 

So lets talk about dosing first. I've helped guys that have won national qualifiers on 1cc of Test E (along with a couple small additions at the end). I've helped a guy that gained 25 lbs on 1cc of Sust EW. So what I'm saying is, if your diet is good, you'll do well on 250mg EW, maybe 500mg EW at the most. I would split your dose into 2 weekly shots, say Monday and Thursday. 

Estrogen mgmt. You want to have some estrogen in your system, but not so much that it causes problems. Dosing is different for everyone. If you use 250mg Test EW, start with .5mg 2 to 3x wk of Adex. This will help reduce the conversion of some of the test into estrogen. You can increase to EOD if needed. 

After the cycle, you'll want to do a solid PCT. 2 wks after last shot, Clomid 100mg ED for a wk, then 2 more wks at 50mg

So read up on the QA and around the net, to better understand estrogen and to understand PCT, as well as the side effects of test, so you can go into this well armed with all the info you can
