if you have parasites, that is when you know to use safe anti- parasite drugs on them. you have nothing to lose. if you inject, you have nothing to lose, if you are sick and dont know what it is, you have nothing to lose. if you are perfectly healthy, guess what, you have nothing to lose.
its safe to use the drugs, its safe to inject them, its should be done on a mass scale, thats what i think.
