I've been on 2 ten week cycles this year of both deca and test400 ( 1 ml of each per week), with 6 weeks off in between. I have had very good results so far but my question is about the time off. I've been told that my time off this time should be about 12 weeks but I have also read about bodybuilders who take their cycles continuously. What is a good rule of thumb for time off between cyles? I don't want to get on a dangerous path so any response will be appreciated.
