I'll second the above 3 posts.
If anyone thinks 5-HTPs effects as a POSTload are placebo, they r crazy.
As Entropope said its effect is scientifically proven to increase serotonin levels.
At the end of an MDMA experience your serotonin levels are LOW. This is an EXTREMELY unnatural state to be in.
Your brain is literally DESPERATE to return to its more natural levels.
Without 5-HTP the process is long and drawn out, relying on Tryptophan from the diet. (A RARE amino acid)
It then must be converted to 5-HTP by enzymes which work relatively slowly and cannot do a lot at a time - why...because until MDMA came along this simply wasnt needed.
Enter HTP. It can be converted to serotonin by other enzymes which work much faster. Yes, when u dont need anymore in the brain, its a waste, and if anything detrimental as u produce excess serotonin in the bloodstream.
However after MDMA your brain is the place its needed and thats where its going. While i dont know the exact numerical comparision, your serotonin levels will return to normal MUCH faster than if u rely on natural processes.
I will not pill without it and i have forgotten what a comedown is. Sure you comedown but u return to the level u left at, not six feet under.
The following day i feel lethargic, tired etc, but thats from staying up all night; i dont generally feel like i have had anything.
As Soma said, and many others i know have too, u forget how good it is, until u have one without it!
I have turned some of my friends from blubbering messes to normal people again within a few hours; and often i tell them its a vitamin supplement which they take themselves anyway.
Bottom line is: 5-HTP is not some magic pill which eliminates all the negative short and long term side-effects of MDMA..but its the closest thing to it that i am currently aware of.
