I did the parasite cleanse several times while on the MC. Didn't seem to interfere with it. After my first cleanse (in which I added the parasite tincture the first 14 days), I followed Russ' advice and did 7 days of tincture, followed by 7 days off, then another 7 days, and then finished it all off with a LF. It seemed to work quite well. God bless and fast on!
