I was toying with the idea of using 1 steroid cycle to jumpstart my fat loss and mass gain. Not sure if it's even a good idea or not, but you guys tell me.
I've been on my current program for 4 weeks now and am showing steady results through my diet and weight training. I was thinking of maybe a 4 week cycle to kick it up a notch and better my strength as well as quicken my fat loss results to get to my goal faster. Here are my stats:

Age 31
height 6'2"
weight 225
BF% 20-23%
free weight lifting program 2 days on 1 day off.
Cardio about 4 times a week

Goal: Get below 12% body fat while gaining lean muscle and strength. Don't necessarily want to loss weight, but could be happy dropping 10 lbs or so if it was fat.

My questions are these:

Would this be a good idea for what I'm trying to accomplish?

About the steroids themselves:
What would be a good one to start with?
What is the easiest to get a hold of?
What would I have to "stack" it with for limited side effects and why?
Would side effects even be an issue with only using for 4 weeks?
Does anyone else do anything similar to this for these kind of goals and how is/did it work out for ya?

Thanks for your time.
