19 years old? Had your hand X-rayed to see the growth plates? Lots of 19 year olds have another inch or so to grow... and roids will stop that. Why not wait a year or two?
I'm planning my first cycle, and I think its gonna be 250mg of Sustanon or Test Cyp, with clomid at the end. Maybe just stick with the Sustanon at the 250mg level? Why stack gear on your first cycle? You can get results from something simple, and safer. You don't know how susceptible you are to gyno, hair loss, etc. Theres no reason to use all that stuff from the start... save that for your second cycle. And have some Nolva on hand in case you start sprouting tits.
Anyway, thats what I've gathered so far. If others have more experience, feel free to shoot me down.
