2C-EF
Extremely limited human data exists for 2C-EF. Start with low doses and verify substance identity via reagent testing or spectroscopy. Avoid combining with serotonergic agents or lithium. The fluorinated structure may result in slower metabolism compared to 2C-E. Use harm reduction practices including volumetric dosing.
