No, because the way it works is by lowering estrogen and in MEN lower estrogen can reduce body fat and expose muscle so makes you look more toned. Also in men, high levels of estrogen can mean low levels of testosterone so SP may help guys with very high estrogen levels. For us gals, we want lower estrogen and lower T and SP seems to do that for us.
Plus, remember, this is just one source of info and we don't really know how much weight to give this claim.
People are having success taking SP and to my way of thinking, real-life success is worth way more than some allegation made by herb salesmen on the Internet!!
