I havent tried anything yet, but do have an unopened packet of Humaworm on my shelf.
I would definitely suggest giving them a shot (he even has a section of the forum), its made fresh, by a very caring team and the person who posts on this forum is a credit to the company, to compassionate alternative healthcare and to a quality product at a more than affordable price!
Although I havent tried it, the testimonials on Ask Humaworm surely speak for themselves!
