In the first part of the video dedicated to amphetamine salts, we prepare an alcoholic solution of freebase amphetamine and obtain saccharin in the acidic H+ form. The second part of the video will be released soon, in which we will demonstrate the preparation of salts from various acids.
The following pharmaceutically acceptable salts of A are known in the literature: 2-hydroxyethanesulfonate, 2-naphthalenesulfonate, 3-hydroxy-2-naphthoate, 3-phenylpropionate, acetate, adipate, alginate, aspartate, benzenesulfonate, benzoate, benzylate, bicarbonate, bisulfate, bitartrate...
I have a pressing machine TDP 5 and an additive to make the pill not break. I need a real partner who can manufacture amphetamine. I am in a country where there is a very large demand. I will guarantee you that we will never be able to cover the customers’ demand.
Great video, thanks for your service. The disadvantage of the acid-alkali purification method is the high loss of substance. I always wash the free base in dichloromethane with water, this will partially remove some of the impurities, and it is also rational to wash the acidified aqueous solution of the amine with small portions of dichloromethane.
A more effective method, in my opinion, is to distill the free base into fractions in a strong vacuum, then you will get a completely colorless main fraction of the free base, and will also reduce the loss of substance and save a large amount of solvent.

Good job guys. I have been on the forum since 2021 and honestly I owe everything to the BB forum. I have been consuming various types of substances since I was 16 and I am 38 and sometimes I think about the amount of money I have wasted buying products on the street that are not actually the product you think you are looking for. Many nights I dream that I get up in the morning, I plug in the computer, I go to the BB page and my shock is such that the police shield appears announcing that they have closed the page. I hope this never happens, but if it does, I want you to know that I will be enormously grateful to you all my life. Great team that you, the creators of BB, form. Human beings would not be what they are today if it were not for those who share their knowledge with others without any type of profit motive. I love you guys, greetings.................................
