Good Luck with this. I think you need to wait a few weeks and do some serious research before you go on cycle. Test only for a first is good advice for many reasons. It's funny about the deca, I got some first thing when I wanted to run a cycle and I still have it laying around untouched.
Seriously, it will be well worth the wait to learn more before you start. It's serious business and can suck if lots of precautions aren't taken. Post here or PM me if you want specifics.
