Hi , first let me start off by saying I have a horrible person worm infection that's all over my body. I have worms in my face head neck back thoracic cavity chest under my breast arms and legs. For I have tried every remedy out there as I was reading through your review I read that you use PZQ pure powder and was curious to what brand you used for I am willing to try it. I live in Dallas Texas where I cannot get any help I've had pneumonia because they made it to inside my lungs and was hospitalized now I'm taking Colloidal SilverMiracle-Mineral-Supplement diatomaceous earth and it all seems to be helping for I do feel better but I must kill these things for once and for all I've lost a ton of weight for I don't even look like myself anymore.. so I started Googling the brands of pure praziquantel powder and was wanting to know what brand you used. Thanks
