well, look at it like this. Making any drug is actually fairly easy if you have the ingredients more than anything. The correct equipment is second because if you can find the chemicals, then you can make the adderal with a few glass jars and coffee filters. If you dont have all the ingredients, thats when it starts to gets hard and this becomes a very long complicated project
Because youre in brazil i have no idea how hard it would be to get the chemicals you need. But you have a decent chance because youre not in the united states, but youre still in a developed country which may have made an effort at blocking access to all chemicals to make drugs...
your main focus like i said already is to look for the chemical called "benzaldehyde" and also for "nitroethane"... if you can find and order this you can do this pretty easily without buying any lab equipment. The lab eqiupment you'd need to make benzaldehyde and nitroethane is pretty extensive....
if you cant find these you can still order them and import them from other countries, mainly china. China will send you anything. Europe also has a few countries that doesnt care if you have access to these chemicals. Like czech republic for example. Thats a common one. The only hurdle with this now is importation with your country's customs. Maybe they care about importing drugs and have an agency to detect illegal importations. Because it is chemicals and not drugs that you are importing, you have a better chance here. The sender can also label the chemicals wrong if you ask them sometimes. That can help getting it into your country. This is how you can get in trouble though. so this step needs much thought
if you make this project all about finding the right chemicals this will actually be fairly easy. The reason to buy any lab equipment is for making chems you cant buy.
you can do this in a jar if you can get the following chemicals.
-Benzladehyde
-Nitroethane
-Sodium borohydride (might take some work but relatively easy)
-Ammonium acetate (possible to get, its not illegal for anything. What is more ideal is the chemical called cyclohexylamine or n-butylamine which are a bit harder to find. But any of these will work)
-99% isopropyl alcohol (easy)
-Sodium hydroxide (easy)
-Sulfuric acid (easy)
-Copper sulfate or copper chloride (easy)
i might be missing something, and if i am its something insignificant.... The major stuff is accounted for... It can be that easy..... With work and lab equipment you can make any of the above chemicals except for the sodium borohydride. If you cant find that, there are easier alternatives...you can use mercury metal, which i avoid, but there is a process using a nickel chloride (easy to find) and zinc powder (also easy to find). but you have to learn how to do a reduction process here instead of just mixing chemicals.. but thats ok it can be done..
