Dont do any cycles that any body told you to do above. You do not have the knowledge you need to succeed. If you want to loose fat and put on muscle, go to Needtobuildmuscle.com, and pick up a bottle of N2burn. Steps to success as follows.
1.Stay away from anabolics for now, you will end of getting hurt or messing something up that you didn't plan on, trust me it happens to a lot of people.
2.Get a gym membership if you don't already have one to a gym that you enjoy and like.
3.Go online and search google for workout plans, something new that you haven't done to get you in the routine.
4.Evaluate your diet. People agree here that diet is undoubtedly the most important factor in gaining muscle, and loosing fat! Stick to high protein meals, easy on the cals, and take in clean carbs
5.Once in a week in the cycle start your N2burn and take regularly.
You will no doubt have a great time, and not look like a fool for taking a quick route that will end up crashing on you because you didn't read. You put in the time, the effort, and the willingness, you will have good gains that STAY with you, quality muscle, and quality fat loss.
Let me know if you need more help.
