Clomid 50 mg/d for 4 weeks. You are pretty young to start AAS. really, you should get off all AAS and stay off for a good 5-7 years and build a base physiques and strength. When young men start so young their is a high risk of damaging your hypothalmus-pituitary-gonadal axis (HPTA) for good. You should do dead lifts, bench press, squats, military presses from the rack, and power cleans from the floor. You can throw in some arm curls and tricep extensions too but the main ones are the others are the ones that will put muscle thickness and strength on you. Then after you are into your 20s that would be the time to think about it after you have put on a good 20-25 lbs of natural mas that will nver go away. 90% of AAS mass will go away over months after you stop them. Build that base and then think about that. Plus, not right now, but in the future you will want to ahve children. Starting now will probably make that very difficult if not impossible. The lymbic and HPTA systems are not really mature until 25 - 27 years of age so keep that in mind.
Good luck,
