It's so obvious but steroids are male hormones. No matter what the dose, the more male hormones, the more male a women becomes. You will see subtle, masculine changes in her, very slowly but they will happen. I saw my ex girlfriend get coarser hair, thicker nails, rougher skin just off Winny V and that was taken at very small doses (up to 5 mg twice a week). We both could not believe the subtle changes like these that were happening to her and no book at the time had listed these as side effects that women would experience.
She should definitely not be on the sauce just to lose fat dude. Get her to hire a top contest-prep trainer to put her on a serious diet and training program and dump her ass if she doesn't stick to it!
