listen to BB and don't be stupid. I'm not trying to be an ass, but you are going to mess your body up for the rest of your life. My younger brother wanted to start when he was 20 and I had to sit him down and show him the facts~its just stupid until your body has completely developed...not to mention your first steroid cycle should be test only. You have to learn how your body reacts to the test and then add compounds in later cycles. If you run more than one compound how are you to know what is messing with your body/giving you sides? Do yourself a HUGE favor kid and take time to read and learn. This is a perfect place for a young person to learn about everything and the later in life (25 IMO) if you still want to start a cycle go for it, but be informed first! Here is a few more links I would suggest.
EDUCATIONAL THREADS
WORKOUT AND TRAINING
DIET AND NUTRITION
Hope you don't go forward with the cycle and I hope some of the literature on this forum helps you understand the importance of waiting until your body has matured. Take care, kid.
