well from an aas point of view.. the most anabolic and lowest in the androgens are andriol or anavar.. both are orals so no shots are involved.. Winny is harsher with more possibilites of sides..
i will say it again.. Most important factors in getting a rock hard body..
1) DIET.. not pretty clean, not pretty good, but CLEAN!!

i mean she is eating her bodyweight in protein and has low carbs which comprise of mostly complex (veggies, potato, oatmeal) and no simple (breads and pastas, simple sugars).. also make sure she is getting moderate fats ie: flax seed oil, omega etc..
2) Weight training
3) Cardio.. moderate to frequent depending on goals..
4) has she tried fat burners?? if she hates jitters and i understand that feeling, she may want to turn to (which is off the market) Norephedrine or a NYC stack.. Minimal jitters and great results..
and as a last resort to break her through a plateau.. aas.. start with the lightest and see how her body reacts..
There are tons of posts and research on anavar, so just hit the search key for more info...
Hope that helps
