Welcome to NeuroTalk:

I really do not think it is wise to use St. John's Wort with 5 HTP.

I would research that for interactions.

There are sites on the web showing the destroyed burned out axons from the serotonin secreting cells in the brain in photos.
These were "burned out" by the release of hydrogen peroxide from the cells when ecstasy is used frequently, and if too frequently the cells cannot recover and atrophy away. So if this is true for humans, then using supplements may not help much.

Much of the ecstasy information is still fluid and changing. When you search use MDMA as a keyword, and you will find more.

I think it is best to try one thing at a time. This is easier to see if it works, and it is easier on your body. Big mixtures of herbs are really difficult. Herbs are actually mini-drugs, and can be poorly gathered and mixed, and even contain contaminants. I would start with the HTP and go from there. It might be all you need after all.

It is however controversial still, but it is thought that ecstasy can permanently change/damage the brain, at this time.
