It is totally fine to run same cycle for many times as long as you give your body enough time to recover.
Your body will not get used to steroids in only 1 cycle and your body will never get used to having blood testosterone level above 2000 as this is supernatural and nowhere near physiological.
Just think of people with hypertension; do they need to change their medications every 6 months or it will not stop working ? the answer is no, they can take the same dose of the same substance for years before requiring to increase the dose or change their meds.
