so when u gonna blast hard then, at an old age when your body is tired and worn out ? 
puberty to 25 is the prime time for growth
I'm 19 still and haven't cycled a lot yet just low dose of tren and prop and then sustanon but I'm thinking maybe wait another 6 months-1year to use high doses but if i stop growing and hit a plateau I'll up doses earlier than that
Maybe this coming fall after my tren cycle I'll run
1g Test E or Sustanon/week
500-750 Deca/week
Oral to kickstart week 1-4 (Maybe anadrol?)
Then I'll probably run a bridge of 500-750 Sustanon till spring/summer and then blast tren and sust
1g Sustanon/week
700-1g tren ace/week
Maybe some mast?
Oral week 1-4 (Probably Anavar)
That should be good for my first high dose blast
