I usually go to a Techno festival once a year (due to my family situation) or if I were very lucky twice. I always take speed, but due the difficult to find nowadays a good amph, when I find a good batch i buy a little more for the next time, but the next time sometimes is even a year later…..I keep it in the fridge or in the freezer, well packed, Is safe to take it after a year? If the speed lost its properties, what does it mean? its power become low or could it become harmful?
Amphetamine and amphetamine derivatives (meth, MDMA, MDA,2C-X, DO-X…) are simple, stable molecules. Their rate of degradation over time is very low, and they can keep their properties during years if they are kept in a dry, dark place, out of direct sunlight. There is no need to keep them in the fridge (in fact, moisture can facilitate degradation). They can be kept for years without problems.
