5-HTP Dangers?

I was reading up on 5-HTP and noticed it has something called "peak X" in it.

I realize in the link people say it has caused vomiting and other BS that is highly unlikely but I have found many other sites talking about this “peak X” and the sickness it causes.

Does anyone know if Biotest or other companies test their 5-HTP for peak X?

I don’t know the answer to your question, but I can’t think of any current Biotest product that uses 5-HTP.

As for other companies, I really have no idea. Sorry.
