The book is decent. It has 8 editions and none of them have subtracted any content, so it’s unnecessarily long. Most of it is already outdated, as precursors have been prohibited or the means have become outrageously expensive.
If you want a somewhat viable option, check out the chapters on oxidating toluene to benzaldehyde, brewing or cooking your own ephedrine and converting that to your favorite molecule (toluene - benzaldehyde - L-PAC - ephedrine - mæth). I don’t quite remember but I think the last step could be done with zinc powder or smth cheap.
I’ve also seen the chemistry of the book be strongly criticized on Erowid and Reddit. I would have no idea as I’m a complete ignorant on the matter, so just watch out. In any case I think the book is good if you want to go from zero knowledge to some. Also keep in mind all this shit is toxic and dirty.
As I said, decent book.
