I started my run nasally about 7 days or so ago, I filter mine, every time since it goes straight to the brain, I have been really surprised at how quickly I felt the results atleast partially, I seem to be calmer, more focused I can actually finish what am working on before moving on to other things in a more organized way, my eyesight seems to have been improving I wanted to say it was placebo, but I didn't know about the eye sight until I looked up it up again! I was journaling my course on Semax and that's what I thought that after I sprayed it I felt like the world was getting brighter and clearer, I don't have so much brain fog and can think a lil bit clearer which is far better then what I hoped for, but one warning I've encountered is if I try and squeeze in another spray about 4 pm am unable to fall asleep. Haha I'm up now 1:15 am reading more on the forum, I need some selank tonight but not yet I'm working my protocols and journaling and doing my research!
