Hey bro, 

Your best option is to start with a test only cycle or test with a short oral kick start. As for dosing, lower doses will result in less side effects. Always use the least you can to evoke the best possible results. As time goes on, your cycles will get more complex and higher dosed. For now, you can do very very well with the plan I will lay out. Remember, that it never needs to be complex. Even the more advanced guys can get awesome results, keeping it simple. Diet, training and rest is key. With your job, you probably burn a lot of cals at work, so in order to make good gains, you will probably require more food than if you had a sedentary lifestyle. 

I would stick with a single ester test for this cycle. This way, you only need to inject 2x wk. Sust is a blend of different test esters. The results would be about the same as a cycle of Test E or Cyp, but due to the shorter half life of some Sust esters, you would require more frequent injections. Along with test, you will want to use a low dose AI to control estrogen. If you find that you are getting estrogen sides, you can increase the dose of the AI. Read and understand what these sides are and how your AI will prevent issues. Also, you will want to do PCT after your cycle, so I would suggest you also read and understand why your need this and how it will help you. I am including a Dbol kick start at a moderate dose. This will get you gaining quickly, while you wait for the Test to kick in. 

1-12

Test e 500mg EW, split into 2 injections per wk

adex .25mg EOD to .5mg EOD as needed. May find you need more on the dbol than after it is finished
