I don't know "how far back they are on making the orders"...
But as far as when your humaworm is made, the way that I understand it the herbs are blended together the day your order is to ship, or possibly the day before. I could smell the freshness of the herbs as soon as I opened my mailer. I've never been able to do that before with anything that I've purchased, even after opening.
The scent was so fresh and pleasant that all my cats within the house came running to sniff at the mailer!!
