]Ive noticed and been told by some workers at the local needle exchange that the normally reliable Portuguese Sus is being counterfeited in huge sums in the UK at the moment ,Ive come across some and it was very well done but when tested in our local university it showed roughly 25% propionate and the rest nut oil so those with allergies beware, the good news was we also tested the Turkish Sus which showed all Esta's were spot on .......just thought i would share this with you as we all want to beat the scammers!!!
