In brief: No go.
5-htp is a precursor to tryptophan the Amino Acid used to create serotonin.
The national institute of health recommends not to use 5-htp until more is known. 5-htp might be unsafe. Some people who have taken it have come down with eosinophilia-myalgia syndrome (ems), a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia).

The relationship between 5 HTP and EMS remains unclear. The original reports were based on L-tryptophan and some have felt the EMS from L-tryptophan was caused by contaminants. Still, I would be cautious about taking 5 HTP. http://www.livestrong.com/article/537529-eosinophilic-myalgia-syndrome-5-htp/
