Tetra Twist Extraction

The Tetra-Twist:
Best extraction method for 120s and 240s Tetra-Twist(NOTE: This is what my collegues consider the BEST method for 120mg and 240mg pseudoephedrine pills. Even more preferred than the STB3. However neither is a Universal Cure. Some pills work better with the STB3, some work better with the Tetra-Twist. The tetra twist requires Tetra, which is hard for some countries to get. So they would probably pick the STB3, but if u live in a place where u can get Tetra and u have some 120s or 240s or a pill that u think could work with this method its worth a shot.)This method is very good, yall better thank me for this one!
