Introduction
Amphetamine and methamphetamine are the most popular synthetic substances and both of them have significant value in modern drug sosiety. They are used at raves, parties, as doping, to get a high and so etc. BB Forum is unique platform in the World, which implements studies of these substances syntheses and post them publicly for free.
In this post, we want to share a comparation of several most popular syntheses methods of amphetamine and methamphetamine. All syntheses was conducted in one laboratory. You can compare their yield, reaction times, relative cost of product, syntheses pros and cons.

Prices for reagents are taken for packing 1l or 1kg.Conclusion
As you can see, the numbers speak for themselves. A reagents availability and syntheses costs are essential characteristics. It is hard to overestimate this data. Every clandestine chemist, who has a plan to produce one of these substances, can evaluate their opportunities with help of these comparison tables and choose the suitable synthesis pathway. Then, they can open a synthesis tutorial and study all details. Part of these syntheses have video instructions.
