phenylalalinne is the arousal ‘love drug’ that’s found in the cocoa beans used to make the chocolates. theobromine is also in there i think it’s effect is more stimulating like caffeine tho.
hmm, long term use wise…maybe some of the newer developed nootropics haven’t been studied as much. the classic ones like piracetam, hydergine and choline have been exhaustively tested in clinical trials and have been quite popular in europe for the past 20 yrs or so.
