Check out Dr. Kalish being interviewed on Underground Wellness w/Sean Croxton: http://undergroundwe....com/tag/5-htp/
5-HTP supplementation is discussed.
Yeh, the UG podcast is good. I have been taking nootropics for years now.
No, there are no down sides to taking 5-HTP, it is a supplement not a drug as it does not have the side effects drugs have.
