over the years i found different makes sust gave me different pains. First time i was using sust from pakistan dammn couldnt sit for weeks. then i moved on to sus from holland = had no pain at injection sites whats so ever, same thing with the local South African sust. Now im using sust from egypt nile , same problems like pakistani one pains evrywhere. They are all organon they should all be the same right? dont know in my opinion the are not at least the same pain wise
