I have made the calculations of the chemicals according to the chemical synthesis of amphetamine documented in the following video tutorial;
If only to obtain 1kg of speed, 2016.19 g of precursor (P2NP) are required and only 2kg of the precursor cost 570 EURO, 3474.8 g of sodium borihydride are also required, only with those two chemicals it is more than 1,000 EURO
