So basically it's you that wants him to get back on roids? As you say its been so long off time for him? Let him do as he wants, I personally would never get involved with a girl serious if she wasnt ok with AAS. Also as MilkDaScow says, everybody assumes from the get go anyway.
Well i have to listen to him whinge and complain 6 days a week. I also am watching his motivation decrease because he knows he's fighting an uphill battle without the aas. Plus it must be hard for him to train with someone on the roids, our strength was once the same and we were in similar condition. now i'm much stronger, leaner and bigger. So yeah, i guess I do want him to get back on, cos i know how much he wants to and misses it.
I personally sat my gf down before we got serious and went through the whole lot with her. i explained it all and said if you want to get serious this is a part of me you'll have to accept. It's all good now. she never questions it.
