married here bro, and my wife knows. (even does my shots!)
I let it our gradually. first told her I have a real scrict supplement regiment and control my TEST and hormone levels with monthly blood work. Then I let he know my test was low and needed to start adding TEST to increase my already low natural production. (make it sound like "hey, it's science....i need it")
then you start adding some trenbolone into the syringe with the Test because it "counters some of the sides". she will never know the difference and soon enough wont give a shit. by then she is used to seeing you stick yourself and it's just normal and shes already gone along with it
