I keep seeing videos of this product, don't know if it's new or not, but I hadn't heard of this particular product. It's very pricey at $124 for a quart. They do have a sample kit you can buy but even that is $75.00. I'm sticking with CA, but this might be a reasonable substitute for those that cannot use CA due to allergies or what have you. If it has a short shelf life that price would be another problem. Anyways just putting it out there if anyone is interested.
