Anavar is really the safest there is for a female. Anything beyond that is going to increase more risks of side effects. If I were her, I would cycle var at least a few more times to get the most out of it before you thinks about moving ahead to something stronger. The next step in AAS would be Primo, IMO. Side effects can be more than var, but they are still lower than other gear, when taken my females. I would start out with 25mg taken IM, 2x wk. After 5 wks, if she is feeling good at that dose and there is nothing going on to worry about, I would possibly consider going to 75mg ED. I would climb no higher than 100mg of preimo for wk. Like any other steroid, this will help her with muscle gain, but also, like any other steroid, it isn't going to really burm much fat. 

GH is a good option for females. It is not a steroid and does not have the same risks in side effects. Over the long term, even a low dose for girls, 1iu ED, would help to reduce body fat, while working toward gaining lean tissue. When used in conjunction with AAS, GH becomes even more effective.
