If she is interested mostly in developing more hardness and vascularity then i think 2-5mg ED would be quite good.
If she wants to add a significant amount of muscle then i would say to still begin with dosages in the 2-5mg area for at least the first 3 weeks of her cycle. If her gains are coming nicely and sides are not bad then stay at that dosage. If sides are too much, then decrese obviously. If she stays arounds 5mg ED then probably after 4-5 weeks she will find her gains slowing or stopping even if they were good before. She might try then 8-10mg ED for another 4-5 weeks.
This is a mild cycle. Low doses. As a AAS virgin she does not need the amounts i need to make nice LBM gains.
