I bought and read this book in 2011 and was blown away. The author, a biochemist is informative without being biased. The balance of the book is impressive. The reader is enabled to make an informed decision in progressing forward with DHEA (or not). The 'fear' factor is dispelled, in as much as one learns to cross-check references to the product in line with personal health issues, gender, age etc. Cherniske also mentions derivatives of DHEA (such as 7-Keto) and where to purchase the products. So overall the reader is left confident in the understanding of the principal of DHEA and where this natural supplement can assist in their daily well-being.
I purchased 7-keto which does not present any of the 'side-effects' that some people experience with 'DHEA' and the results were remarkable. I took 1 25mg per day. I now take (after 2 years or so) 1 x 25mg every other day. I find this is all I need. The impact is immediate, so when you stop taking it, it is no longer in your system. Particularly good if you don't like how this makes you feel (unlikely however).
I immediately bought six books for the family and friends I knew would benefit from reading and ultimately taking 7-Keto. Some had remarked on my 'upliftedness etc. '. All but one, now use 7-keto and had symtoms of Fibromyalgia, Parkinsons, Arthritus, Menopause and M.S. All have better, pain-free days.
I would highly recommend this book and the topical product.
