I've used MDMA for a few years now and I've never had any success with 5HTP to assist with the comedown/recovery time. As far as I know there have not been any studies performed involving human beings with 5HTP and MDMA recovery. So now it looks like general opinion/ recorded anecdotal evidence is the best we're going to get.
Please take the time to answer the poll. The more responses we have, the more confident we can be about the usefulness of 5HTP.
If can add more options later if needed
Your vote: Yes as above, but there are side effects such as drowsiness and headaches.
