Serotonin has signalling roles in the gut etc. as well as the brain. Wikipedia tells me it can trigger both vomiting and diarrhea, so maybe 5HTP is a better choice for that reason?
Nope, that's not it;

Serotonin taken orally does not pass into the serotonergic pathways of the central nervous system, because it does not cross the blood–brain barrier. However, tryptophan and its metabolite 5-hydroxytryptophan (5-HTP), from which serotonin is synthesized, does cross the blood–brain barrier.

That was my other guess, but you have to call your shots, or they don't count.  |
