Listen kid, wait a while. You are 19 years old and only 165 and only been training for 1 year. You can grow naturally and get to 190 over the next 2 years, YOU CAN.
Get some solid foundation training in b4 you go on and you will be glad that you did. Do lots of squats, deads, barbell curls, dips, benching, etc. the basic compound movements.
If you get to 190-195 on your own (clean) and then go on a cycle you will alsways retain that hard earned natural muscle when you go off the juice.
Please do not do anything stupid at your age. I hate to sound like a father telling a child what to do but don't feel pressured by the other kids your age taking AAS with very little fundamentals.
Peace
