BIOHACKING I'm selling this after reading it. The book has a slight warp, the cover has some scratches and slight creasing, and there are dog-ears on the corners of the text on 6 pages, and some wear on the edges, but otherwise, it's generally in good condition. I think it's in "average" condition for a used book. It seems to be unavailable on Amazon at the moment. *Please refrain from price negotiations due to my busy schedule. Thank you for looking.
