19. HOW CAN I PURIFY MY SPEED?

There are a few different methods for purifying amphetamine, but one of the simplest and best ways to do this is with a dual solvent re-crystallisation. If you plan to do this however, be prepared for a LARGE reduction in volume. Keep in mind however the stuff you separate out isn't really any good to you anyway. Consider the fact that most street speed is less than 15% pure, which means the gram you just bought has about less than 150mg of active content. If done extremely carefully you won't lose much of the actual speed.

Re-crystallisation is based on the different saturation levels of hot and cold solvent. A saturated solution is one which has the maximum amount of solute dissolved in it. The saturation level of any given solvent rises and falls with the temperature. Put simply, when a solvent is heated it can dissolve a larger volume of solute, and as it cools and the saturation level drops, excess solute will form into crystals and sink to the bottom.

A simple purification can be done using a single solvent. Add hot solvent to the amphetamine in small amounts until it is all dissolved. Anything that will not dissolve is adulterant and should be filtered out using coffee filters or filter paper (mositen filters first to prevent them soaking up solution). Next, allow the solution to cool slowly to room temperature, then place it in the fridge and allow it to cool further. Once it has cooled in the fridge filter the crystals out and allow them to dry.....................
