Are you actually serious or trolling?
Why would you want to get your girlfriend on a cycle?
If she is a beginner she should stay FAAAAAAAAAAAAR away from any kind of cycles.
If she is just starting out, steroids should not be in her vocabulary. When she has years of training under her belt, have her come back and ask herself. Women need to be very careful with what steroids and dosages they use or risk permanent virilization.
