Methysergide/Deseril/Sansert

Apparently the chemistry is very similar to LSD. They're prescription migraine medication, and apparently not too hard to get a prescription for. But this is a bit of a hassle to do. Has anyone taken this?

 

lol this post came up on a google search... burrrrmp...

 

There are rumors that there is a psychedelic effect starting as low as 4 mg. I expect though that escaslating the dose will not produce full blown psychedelia as it will then fully antagonize the receptor. LSD chemistry is usually fairly complex, conversion would require indole demtheylation of the nitrogen and replacing the hydroxybutyl group with DEN. There is no simple exchange reaction so doing so would require ripping down more of the molecule and a more complex addition.
