In fact, I tried to get a prescription for
Depo Provera (used in chemical castrations outside
of the US), but was to no avail.
I've read a lot of conflicting opinions about things like Saw Palmetto, Licorice Root and Reishi Mushroom extract. Some say they have killed their libido, others say they were kicked into overdrive. I've taken significant amounts of Licorice and Chasteberry, but have not noticed any impact.
