I guess I really am old school. If you hide something important to you, from your wife, well most generally the marriage won't last a life time. I mean I'm talking about spouses not being honest with each other.
This topic is carries many opinions and I will say that there might be an occasion for not being honest 100% with something. But as important as this is in our lives , we who love AAS, it isn't being fair to even ourselves, to hide it. Coming up later and untold can have many more complications.
My wife never liked it but she did stand by me. I myself have one (1) big secret from her but it wasn't anything I was going to continue indulging. That's over and to reveal would hurt her to the bone, and to this day. So I carry the secret and after being married 36 years and divorced 2 I live with it. In this case and point there is no point to reveal and hurt her so.
I think IMOP more than not it should be discussed. The honesty and the caring of each others love for the activities that so make up who we are need companionship at most all levels.
My 2 cents
PS: Do you guys really think after a few cycles she won't figure it out. Hmm maybe if you aren't very successful with your cycling
