Don't go there, too strong, even 1/10 of a ml at that potency is too much.
Be aware that if you were to go ahead, at even doses as low as 5 mg a week (I'm talking subcutaneously or topically, not orals) taken over a long enough period of time (several weeks/months), side effect could include: her hair thinning, sprouting new facial/body hair (not a lot, but a few new hairs for sure), her voice might drop a pinch. Mood swings (more like serious short tempered-ness that comes suddenly, that usually clears within the first six weeks or so). Her sex drive would probably go up, her clit might swell a little (temporary), she may even become multiorgasmic if she isn't already (again, temporary, with the hormone increase) but her body might overall thicken (permanently) too, particularly if she's lifting. She might gain weight (in both fat and muscle) she'll almost definitely hold a shitload of water.
If she's really serious and you're up for it PM me, I'll give you a few ideas. Women respond better to a topical application and there are ways you could produce a safe product for a woman.
