>>10139072Huperzine 1%, most racetams, L-tyrosine, L-theanine, Uridine mono phosphate, ALCAR, lions mane, Adderall (I don’t consider a nootropic), noopept, caffeine, etc. Most work but every brain is different. I tend to do a different stack everyday so I don’t hit tolerance. Favorite stack is a caffeine + L-theanine + plus any memory recall nootropic before an exam.
