I just found this primal world a month or so ago thanks to an Amazon recommendation. Given that I was at primal square one, I ordered the kit a received it literally within 2 days. The kit is tremendously well designed and presented and the description of the contents on the Primalblueprint website is spot on.
The kit has tons of info, but does not just repeat everything in the Primal Blueprint book. As I said, it has a ton of info, but more importantly, a set of strategies and activities and cheat sheets to help you adopt all aspects.of the blueprint. I like it a lot, but if you're an "expert" Grok then you may not need it.
