This is pretty scary serious stuff.

A woman at a nightclub on Saturday night was taken by 5 men, who according to hospital and police reports, gang raped her before dumping her.

Unable to remember the events of the evening, tests later confirmed
the repeat rapes along with traces of Rohypnol in her blood, was
Progesterex, which is essentially a small sterilisation pill.
The drug now being used by rapists at parties to rape AND sterilise
their victims. Progesterex is available to vets to sterilise large
animals. Rumour has it that Progesterex is being used together with
Rohypnol, the date rape drug. As with Rohypnol, all they have to do is
drop it into the girls drink. The girl can't remember a thing the
next morning, of all that had taken place the night before. Progesterex, which dissolves in drinks just as easily, is such that the victim doesn't conceive from the rape and the rapist needn't worry about having a paternity test identifying him months later.

The drugs effects ARE NOT TEMPORARY- They are PERMANENT!!!
Progesterex was designed to sterilise horses. Any female who takes it WILL NEVER BE ABLE TO CONCEIVE.

The b*stards can get this drug from anyone who is in the vet school or any university. It's that easy, and Progesterex is about to break out big everywhere.
Believe it or not, there are
even sites on the internet telling people how to use it.

Be careful when you're out, and don't leave your drink unattended.

Please make the effort to pass this onto all you know...
Guys, please inform all your female friends and relatives. This has
now been reported to have been used on 360 women around London.
Girls, keep your drinks safe at all times.
