Interesting thougts, but I´m not sure if Valium would kill anything. It sounds like it would just put them to sleep or slow them down to me and it could possibly be dangerous to take a large amount of that, as well as steroids and hormones. It seems to me in my personal case that they do get effected by various drugs, but not as affected as I might get if taking a large amount of anything. I have taken large amounts of Valium and it didn´t kill them, they were just put to sleep for about two days after that. But I wouldn´t write about it on the forum as a suggestion before or after trying that, or any other strange method I tried unless I tried it myself and had some type of positive effect from it. It could be that someone would actually follow these suggestions and end up dead or toxicated.
