My wife knows and has no problem with it. It makes her feel more comfortable that my friends who work in the field of medicine, also use AAS. Heck, she even reminds me when I have to take an injection.
I have an app on my phone called "Med Helper" and it truly is a magnificent app. It's for droid phones but I'm sure there is something similar or the same for iphones. It's free, and sends you an alert whenever you have to take something....be it an injection or oral, or any other medication that you might be taking. You can also enter in the desired dose in mg,ml, etc. You can also make side notes that say where to pin, where was your last injection site, etc. It also tells you how much you have left and when you need to order more, etc. You don't need to use all the options, but they are there to help you.
As for my wife, she actually likes to give me the injection. I don't like turning around and doing glute shots on my own, but I have no problem doing them as I'm used to it after 20 years. My wife asks me when I'm going to hit a glute so she can do it for me. Honesty is the best policy. She has her GH, var, clen, T3 that she uses....and I have my shit. She can handle MTII and get dark, I get sick as a dog for days if I mess with that stuff. SUCKS! My wife is actually on this board....
