The Sonoran Desert Toad (Incilius alvarius, formerly Bufo alvarius) is native to the desert regions of northern Mexico and the southwestern United States. Its parotoid glands secrete 5-MeO-DMT — one of the most potent psychoactive compounds known. Mexico is the centre of both ceremonial and clinical 5-MeO-DMT work.
5-MeO-DMT is a tryptamine, structurally related to DMT but with a methoxy group that makes it considerably more potent and shorter-acting. Effects typically last 15–30 minutes when vaporised, with a very rapid onset. Subjective reports often describe a complete dissolution of self — more profound and less imagistic than classical psychedelics like psilocybin or LSD.
Two sourcing options exist: toad-derived secretion, harvested from the Sonoran Desert Toad's parotoid glands, and synthetic 5-MeO-DMT, manufactured in a laboratory. Toad-derived secretion contains additional compounds and varies in concentration, making dose precision difficult. Synthetic 5-MeO-DMT offers known purity and exact dosing, and avoids ecological pressure on the toad — populations are reportedly declining due to over-harvesting. Most clinical research uses synthetic.
Tepoztlán in Morelos has emerged as the global research hub for 5-MeO-DMT, anchored by Tandava Retreats and its University College London research partnership. See research statistics.
