Tryptophan
Basics
DESCRIPTION #
L-Tryptophan and 5-HTP are amino acids sold as nutritional supplements and are used by the body as precursors for the neurotransmitter serotonin (5-hydroxy-tryptamine). Both 5-HTP and L-Tryptophan have been used by body builders as an amino-acid. Trytophan is used to help stabilize mood, as a sleep aid, and by some ecstasy and psychedelic users because they are reputed to both increase the effects of substances as well as easing the comedown and helping stabilize mood the day after.
