It is a VERY good general summary of what is out there that works. Not near as in depth and technical as I hoped it would be, but the supplement world would be a much better place if everyone owned a copy of it.
The best legal fat burner would be either ephedrine,yohimbine,usnic acid,caffeine(combined with a thermogenic), norephedrine, or a combination of them.
I don't know what his book will say, theres no secrets.
Although I credit Will for compiling all of that info and putting it all in one place in a well organized, unbiased
format, there is absolutely nothing revolutionary in his ebook. I was quite disappointed that I paid that much money for stuff that I had already picked up by carefully following a few newsgroups and websites. However, if you are new to the game, it might be a good source to start with. Otherwise, skip it!
