I've had it once, they grow in the forest we do raves in, i didn't experience any bad gut but i did them on an empty stomach after a few days upon fet and garys. Was pretty sleepy effects everything was abit brighter not majorly trippy but i had only eaten a 3rd of a cap and been doing 2ce's and foxy's the week before.
I slept really well for the next week and had really vivid dreams.
An old psychonaut in our town said if you boil them in milk and sugar you can take a generous dose and go to the moon, planning on trying that as soon as they are back out here.
