Try not to be seduced by the claims of 'pure' coke, if your hitting 60%+ purity rate you are buying the best gear available on SR, not much leaves South America over 70% these days and is cut at point of manufacture with amph, leva, ephedrine etc so all the claims of 80+% are BS. The washed coke which should in theory yield a higher purity rate also seems to attract variable feedback so chose your vendors carefully.
