I can't really speak from experience, but I am actually looking into peptides. Particularly TB-500. Now I don't see anything saying a female can not use it, actually I see where the first human trial was actually a female. This would probably be a better route to go then an anabolic or steroid.
Now just an FYI, this substance is tested for by anti-doping agencies. If you are a current or future competitive athlete you really need to research the product along with your sports doping policies.
