Okay, you're going to hear this a lot from your post. So, let me get mine in first.
At 18 years old, and only "about one year" of training, you're nowhere near your natural potential. You will do yourself more damage than good by starting PH or AAS cycles. You aren't even done growing or filling out. Give it some time before you jump in and dable with these compounds. Diet, training, supps., should be the order. Get a good, sound diet, and follow it up with a proper training program. Look into compound movements, rather then all the fancy, defining lifts. Get some protein and maybe some other supps into your regime. Such as creatine, flax oil, fish oil, etc.
There are plenty of threads here that you can read and will help you.
Also, there are better things rather than M1T for a first cycle. but, I will not entertain that right now.
If you have any other questions, just ask. Most of the members here will lead you in the right direction.
