Legend!
Now, where do I get HBr in required quantities and concentration in the EU as a casual consumer? Is making it at home the only way? Similarly, how do I get or I purify hydrogen peroxide to 35 % when all I can get is max 10 %?

I would do it like this we get 4methylenopropiophenone per 100ml 150g 2b4m used 750ml ethyl acetate methylamine hcl 195g/naoh 105g+distilled water 150ml rinse 3 times with distilled water, 450 ml each (total 1.4 l) and hbr acid to pH 5 if the powder is brown, use water and NACI salt, heat the whole thing and put it in the freezer at -18°, then the whole NaCI will remove the dirt crystallization mmc powder + tap water or tap water and ipa 1g mmc to 0.8ml of water heat the saturated solution slightly, set aside at room temperature and the next day we have a crystal or use 1g of powder 0.8ml tap water and 0.2ml ipa and do the same as with just water

Hello master, I will make this synthesis soon. briefly how to prepare 40% solution using methylamine HCl and ipa?
I know the Noah way, I am a bit confused about this.

35% and 12%, seems like it's about hydrogen peroxide.. you can use 12% in all cases just change proportions. H2O2 can also easily be purified by evaporating off the water under vacuum (heat no more than 80c) . Only problem then is you don't really know the exact concentration afterwards and your hands won't like any of it on them either.
Furthermore you really should not be afraid of buying chemicals. No one will report anything suspicious, and the type or amount of substance doesn't make it suspicious. Its behavior that does (strange addresses, Po boxes, wanting to pay cash, wanting to pick it up etc).
