Imagine this: you’re standing in a medicine cabinet jungle. Rows of orange bottles glare at you, their labels listing doses you can’t miss, days you can’t forget, and side effects you wish you could. These are SSRIs, the reigning monarchs of modern depression treatment. They work for some, but at a price—daily doses, months to kick in, and a risk of everything unraveling if you stop too quickly. It’s like building a house of cards only to have it topple at the first sneeze.

Now, step outside that jungle and take a breath of sea air. Enter CYB003, a new kind of treatment from Cybin that’s less "endless commitment" and more "reset and refresh." CYB003 is a proprietary deuterated psilocin molecule—which is science-speak for “we’ve taken the active ingredient in psychedelic mushrooms, optimized it for your brain, and given it a job.” Psilocin belongs to the indoleamine family, molecules structurally similar to serotonin, and works by activating 5-HT2A receptors in your brain. The result? A cascade of effects that can potentially reset how your brain processes depression.
