DMSO can be bought from specialist suppliers – see link below or is available on sites such as Amazon or eBay. You should always buy high purity DMSO ( 0ver 99.9% ) intended for use in medicinal products and not industrial DMSO or DMSO intended for other uses. High purity DMSO has been in short supply for the last year or two and the wholesale price has increased dramatically so care needs to be taken to ensure you are buying it from a reputable supplier.
