Another option would be androsterone from IdeaLabs, which can even be applied directly to the vocal chords.Finally a useful reply. But Jing, you're oriental, which means you have a genetic propensity for low androgenicity. Steroids won't have much of an effect on secondary male characteristics in your case (not trying to be a **** but some people respond better to steroids). I HAVE heard many anecdotes of steroids deepening male voices before, just look on the internet, so I'm convinced it can be done somehow.
