My experience is that I bought some, put it in my storage and now think about it and look at it once in a while but I haven't tried it yet.
There are Pros and Cons with it of course and I may try some (maybe one vial) of it someday but I'd be careful and try to stay on top of my estrogen, etc..
I may also decide to not bother though as I know I don't really need to and it would mainly just be for curiosity because I prefer to experience things on my own before I can talk about them.
I don't know if you know the history of Ment (male contraceptive, etc.) but it's worth researching so you are aware.
Thank you & good luck,
OD
