I didn't like his first reply (Retard Alert....) but after reading more, I have to agree. If you're going to do gear, do it right. Take the time to plan your cycle, do your research, find a legit source, plan your PCT, map out your diet, get it all together and then do it.
Sit down with your girl and find out why she doesn't want you using gear. I would bet she is misinformed like the majority of America on what aas really do. Show her this board, show her the research you have done, the cycle you are planning, how you will run it, PCT diet, etc, your goals, what to expect as far as sides goes. If after she is informed and she is still against it, punch her in her vagina and get rid of her. In 12 weeks, you'll be a whole new man and won't need her. That's my advice.
And oh yeah, Big Cracker is spot on, absolutely right.
