If you are planning to cruise, then the assumption is that you are OK with a permanent shutdown of your natural T production in which case...you don't cruise for a period of time...you cruise/TRT basically forever. TRT/cruising dosages are typically around 150-175mg/week.
TRT is not something you start and stop. It's something you do for the rest of your life.
I really don't recommend TRT unless it's necessary. It's always best to maintain proper HPTA health and do cycles with PCTs and adequate time off in-between
