My wife has always been against "Roids!" Always, until one day, I was straight up and honest to her. I explained to her the benefits, possible side effects, and why I wanted to use. I also told her, if you see a change in me (negatively) that I would stop 100% clean. You know what, she was a go! She pins me every time! She's a nurse as well, so she pins very nicely I might add... Not a sex addict like yours so the sex drive made no difference exceott for me! The Test woke me up! LOL! She also liked the size gain, and joins me every day in the gym.
I'd sit her down first, explain to her honestly your thoughts, make sure she knows you're not on it yet, and go from there. If she's a go! Awesome! If she's not, then you figure out if it's worth hiding and possibly get caught for. If it is, just be good at it!
