Well, sort of stupid question (I did the search and found nothing, okay? ) so: ironically I have access to some chems like DMSO, DMFA, isopropanole and PEG, but don't have to IPM and this is crucial for the recipe. In the EU there's no source of OTC chems as far as I know (one needs certain lisence or something to get the stuff shipped) and the oversea orders are a pain in the ass so could one use some gel or whatever else bought in a drug/pharmacy store and use it as a matrix? When yes, which one?
