If that is for your girl - definitely not winstrol. It is one of the most androgenic compounds, so it will have a much higher probability of causing her virilization side effects, and there is nothing good about them. What's more, if all she wants to do is cut, she would be much better off with Cardarine GW or SR9009 instead of anavar. These are non-hormonal compounds that will not cause side effects. They are very effective, and they will give a huge athletic boost.
