Dude. Please. no.
First - deca - NO. Winny - hate it.
Before I even bother discussing aas for chix ---
1) is her diet optimized? the drugs are irrelevant if she doesnt' have her diet tweaked to get the results she's looking for by itself - i.e. you want to cut -- cutting diet w/ carb rotation. she wants to build muscle - gotta fuel to feed the muscle.
2) If she's interested in cycling, SHE NEEDS TO DO THE RESEARCH -- get her to post up on here (women's board will get better responses than from guys!!!!) and do the research. She needs to know the information to be able to make an informed decision.
I would NOT suggest deca or winny as a first cycle. ASSUMIGN SHE HAS EDUCATED HERSELF ENOUGH to make an informed decision, know what to expect from both the results AND the sides, suggest var.
