Perspectives

“Dang this drug is fun, I don't think I've encountered a better party drug. It's not necessarily deep or empathogenic or anything, its overall quality is that it's just plain fun.”

— Nervewing, nervewing.blogspot.com 25 mg oral

“Overall 2C-B-FLY produced a decent ride, providing a more frivolous and physical contrast to my preferred psychedelics.”

— Dominic Milton Trott, The Drug Users Bible 10–15 mg oral
