i wouldn't buy any supplement whose name is after real steroids, like Diana's balls etc.
second, while herbals CAN be powerful supplements, they can in no way compare to chemically engineered compounds AND it is my knowledge any of the "herbal steroid" i have ever reviewed contains a bunch of ingredients to look like a catch-all "breakthrough", yet these herbs are not standardized (=no guarantee of actual % of active chemicals hence you're buying hay ) and/or dosages are so low they wouldn't sort any effect anyway.
