I have no clue what Colosan is; but you will have no need for Humaworm. There is no problem with taking Humaworm; as it is a bunch of herbs (food). The Miracle-Mineral-Supplement will work better. Humaworm is only for a month anyway. I took it the month before I discovered Miracle-Mineral-Supplement . Believe me, the Miracle-Mineral-Supplement still purged parasites; even after Humaworm. If you take them together, your liver and other immune system organs will be overworked. You may end up quiting.
If you don't want to waste your money, you could take the Humaworm course followed by the MMS protocol. I'd advise, not together.
