read this before buying tryptophan

first of all i have used it for more than 4 weeks and haven't noticed any change and second of all i found out today that tryptophan is unsafe and has some serious side effects and if i knew about that earlier i wouldn't have bought it. it is not safe people so don't risk your life for it.

Can't give you a review, shipment took 19 days to get here. Only received them yesterday and have only had three pills. What can I say!
