Spirotone's active ingredient says is Spironolactone - SPIRO in short, and has been used just as is stated for this medication also, to develop feminization in transsexuals - amongst other things like hypertension control, reducing water retention, etc. etc.
Taken on its own (which I personally did not, I took Spiro with E) it would suppress T production and also MAY stimulate breast growth i.e. it is a T blocker when used this way.
It all depends on one's specific reactions as is the case with most any medication. It did squat for breast growth for me... even when taken E along with it.
It certainly dropped my T quite low, almost too low, and I had to watch out for high potassium containing foods, bananas, figs, potatoes, and so on.
Maybe you would want to ask your question about Spironolactone also? I think it be better known by that.
Just a suggestion though,
