Hi Barkingworm,
Welcome to the DMT-Nexus. You can find some elementary info here:

(But you can use also other serious internet resources for finding more info)
I strongly suggest that you do
a lot of research before you decide to embark on a journey on your own, as this can be a potentially dangerous undertaking. So please don´t look into recipe/dosage questions only, but do a thorough study on diet (important!), set and setting etc...
Have you also considered drinking Ayahuasca in a circle / with a proper shaman?
Do you have some previous experience with other psychedelics/entheogens?
