To be completely honest, you're not ready for a cycle like this. First, you're 18 years old w/2 years lifting experience. If there needs to be a second, you should be below 12% BF to see best results from this cycle. Something a more experienced lifter and dieter will know how to get to.
Continue your MMA training and construct a solid diet to achieve your goals. Nice you're doing your research but you need to research the damage you could do to yourself by shutting down your natural production at your age. It's simply not worth the risk in my opinion.
Here's a little something to get you started.

Stick around and learn. Ask plenty of questions. Your time will be here before you know it.
