Maybe I'll get downvoted for this, but I don't think women should take ANY kind of AAS unless they are planning on competing in something physique or strength related and fully know and accept the possible (permanent) side effects. There's a reason the second A in AAS stands for "Androgenic". Is it really worth the potentially permanent virilization side effects just so she can look good for one summer? She'll probably lose the majority of her gains once she comes off the var anyway. If her clit gets enlarged or her voice deepens, she won't be losing that ever, though.
