I'm less concerned with the age and more concerned with the fact you want to run 3 compounds for a first cycle. Most here will suggest a test only cycle. See how your body responds to test first, sides, etc... then you can add something on your next cycle.
If you were to experience bad sides, you wouldn't know which compound was causing it, and could get yourself in trouble...
My vote, if you're definitely going to cycle, is test e, upwards of 12 weeks.
