favourite nootropics you have experience with?

Just order 10x10ml of Adamax 5mg and 10x10ml of Selank 5mg gonna make my own 250mcg/spray nasal spray out of them since its cheaper to diy it and pretty easy

wondering what your fav nootropics are if youve tried, or even if you havent

ive tried selank semax and noopept and semax is by far my favourite but i imagine adamax will take that spot since its similar thing on steroids
