Advertised as New but was used

This is not a review but a critique. The book was advertised as new and I paid the "new" price, but it was used. There were several pages with penciled-in answers. The book itself is Murray's usual fine work.

Incomplete and full of inconsistencies

While this book presents some interesting and possibly even helpful information, Murray destroys his credibility by his glaring contradictions. For example, on page 33 he says, "5-HTP...cannot be metabolized by the liver into kynurenine." Then on page 238 he says, "...if vitamin B6 levels are low, then more 5-HTP will get converted in the liver into another substance, kynurenine."

Another troubling oversight is that Murray's mention of eosinophilia-myalgia syndrome is very brief, and is in reference only to the L-tryptophan scare of 1989. He never mentions that 5-HTP has also been linked with EMS. He also states that the manufacturing process of 5-HTP prevents any possible contamination, which simply isn't true.

I read this book hoping to find reassuring information about the safety of 5-HTP, but in light of Murray's poor research, inconsistencies and inaccuracies, it's hard to trust any of the information presented.

Don't Worry, Be Happy!

I have suffered from mild depression for years. The therapy described in the book has worked like a miracle.
