I added 5mg to about 10ml of water and a tiny bit of DMSO nasal spray and dosed about 45-100mcg every night.
I noticed:
much heavier sleep
dreaming and dream recall (unusual for me)
melatonin-like effects seconds after administration (less energetic, more relaxed)
unlike when using melatonin I was not tired when waking up
higher libido upon waking up and later during the day
growth hormone/igf-1-like effects upon waking (jaw clicking, feet tight, I am sensitive to igf-1)
feeling more rested when waking up
weirdly enough bags under my eyes (I never have bags under my eyes)
headache which lasts for days even after cessation
