So i have been subq up to 0.4mg of both NA-Semax and NA-Selank everyday for 2 weeks, didn't feel anything difference, no side effects or what so ever. So i took a week off, and dose straight up 1mg right after, now i finally feel something, it feels exactly like drinking tons of coffee but without the jittery, huge energy boost, hyperfocus, my vision changed a little like everything looks brighter and more contrast? I felt the effect in less than 30 minutes but only last about 2-3 hours or so.
Fun experience but will i do it again? Probably not because i could just drink coffee, and they didn't last long enough, plus i don't really need it.
Just my anecdote.
