I am on day three of my second Humaworm cleanse. Today I passed dozens of tiny parasites.They are white, threadlike and less than 1/2 long. A cannot think of anything I have eaten that might have that kind of appearance in stool. I feel pretty certain that they are indeed parasites, but I have no idea what they might be. I only have a twenty two day supply of Humaworm thanks to some thieving dogs, so its good to see positive results so soon.
