    Summary Erowid TripSit PsychonautWiki

    L-Tryptophan is an essential amino acid, meaning the human body does not produce it naturally, but is required for the body's healthy functioning. L-Tryptophan is present in a wide range of foods including beans, nuts, milk, and poultry. L-Tryptophan is a precursor to 5-HTP (which is a precursor to serotonin) and is sold as a sleep aid and mood enhancer.

    First, some very light background info that I think may be relevant. I'm a somewhat heavy drinker, a nightly cannabis user for insomnia and I take 3mg of melatonin as well.

    After reading much about it and being able to get 7 pills for free, 5-HTP was going to be my next drug experiment. I'm 6'3”, weigh around 177lbs. Day 1: Took it during the night, got kinda drowsy, stomach upset because I hadn't eaten before taking it.

    My First week at college I went to a pretty cool off-campus party. Lots of beer, negligble weed, and one stoner with a bottle of 5-htp. Backtracking a little. This was the first week of college. I was very involved in mdma especially this last summer.

    To get the pharmacalogically important info out of the way, at the time of my first recreational 5-HTP experience, I was 14, about 6' 2' (probably a little shorter), about 200 lbs, and had smoked pot and done vicodin previously. I had previous experience with 5-HTP as a mood lifter, and it worked admirably at that.

    My names Dylan, I’m a nineteen-year-old male, and live in Albuquerque, New Mexico. I weigh 135lbs, am 5’8, and my hobby’s are: going to the gym a couple times a week, hanging out with friends, beat-boxing, writing, free-styling, and writing poetry.
