Descriptors

An intensely animalic indole derivative — deeply fecal and narcotic at full strength, with a warm, almost tar-like undertone. On dry-down it opens into a heady white-floral facet reminiscent of jasmine and orange blossom, adding radiant depth and a naturalistic, skin-like warmth. Powerful and polarising; strictly a trace-dose material.AI · claude-opus-4-7
