most tryptamines are relativly easy to make. if you read TiHKAL: The Continuation (Tryptamines I Have Known And Loved; the sequal to PiHKAL mentioned above) most synthesises mainly require either Indole or Tryptamine and certain salts depending on what the tryptamine is. DMT might be something to take a look at. btw, both PiHKAL and TiHKAL are availiable free on erowid.
