the least she can use, the better. Never a need for the harsher drugs. Understand that all of these steroids are based off of testosterone, the hormone that makes us male. So the more she uss, the more she will take on male character traits. So Anavar is a great place to start and she should be able to get through YEARS of gear use and make good progress without more than that. There are many drugs that will give you strong side effects that may never go away. Some competiters use winstrol. This is common. It is also very well known for giving females a deeper voice. FOr a woman that is pushing hard toward extreme goals, this might not be a concern. For a woman that just loves to work out and wants an edge, things like this or permanent facial hair growth might not be worth it. I would suggest she does her own research and if she wants to, that she comes here to ask her own questions. That would tell me that she is in fact invested and she is doing the work to understand the risks/rewards. 

After var, of which she should get results on many cycles of no more than 10mg a day, she could try a low dose of primo. 50mg EW to start and then work up to 100mg at most. But she could go through a few years of just var cycles off and on and probably reach her goals that way, assuming her diet and training are correct. No matter what she takes, diet and training will be the main factors, getting her to her goals

GH is another option. 1iu a day would be enough to see a change, help with fat loss and increase pumps, fullness and muscle growth. There can be some side effects with this, but not as dramatic as with steroids, since it is not specifically a male hormone
