This book doesn’t add much if you’ve already read or listened to you tubes about it, but the author does give links for further info. He also gives the name of a place in the UK where you can purchase without a prescription, and the price is better than what I’ve seen, but I’ve been trying to order for a couple weeks now. The first two communications were prompt but not enough to fulfill the order, and I can never get anyone on the phone. Another employee emailed a form for me to fill out to purchase via e-check, but the form didn’t work and in the previous communication was told not to send any info via email, but to call. I tried leaving a message with the info but no action taken on that. I realize my ordering experience isn’t a review but wanted to share in case anyone else tries to order through them.
