Yes, the L-cyestine is a sulphur compound and an amino acid. It works to paralyze the Ascaris and to destroy their skin. I read that when their skin is gone they die. These worms come out with no skin, are creamish/off white and thick, can be thick as a pencil.
Sometimes I take 4 pills 3 times a day and sometimes I take 6 pills twice a day. I like to take 4 to 6 pills morning and just before bedtime works well for me, always take on an empty stomach.
These are the hardest roundworm to kill. Good luck, I hope you do see some...heyjude
