How do you racemize it? I haven`t heard about such method.

I would simply discard of L-amphetamine tartarate otherwise what is the point of separation? I think tartarate salts are rather hydrophilic, they absorb water so storing them becomes more problematic, just like Amphetamine-HCL. This is why sulphate/phosphate salts are more desirable.

Thank you Ihatemybitchwife. It looks to me that the best/easiest way is the route to start from Vanillin especially because it is readily available. Can someone more experienced confirm/deniy this?

It is extremely dangerous to cut meth with fentanyl. Higgs what is `glycidates` exactly, is it a group name of molecules? If yes, which one exactly is the best for getting BMK? thank you

Where can 3,4,5 trimetoxybenzaldehyde be bought? Or is there a way to synthesize this? I haven`t found anything in the forum. Any advice would be appreciated. The rest of the starting materials are relatively easy to get.

And part 3:

Please find attached the video Cooking Crank with Uncle Fester. It is quite poor quality VHS rip but still everything is visible enough to know what he is doing using only the simplest equipment possible. The video has been split in 3 parts for the upload, but if someone can do a good...

Hi Patton, thank you for clarifying this. My confusion came from the Erowid write-up where they suggest getting rid of the PEG by soaking the initial mixture in Toluene, so I started to wonder whether some of the PEG will remain in the Toluene. Here is the right process in my understanding...

Which lab supply company do you recommend as the best price/value ratio? thank you for any advice.

Hi, can someone please share a reliable supplier of 2-bromo-4-Methylpropiophenone or 4-methylpropiophenone in Europe please? PM ime if no ads in the forum here is allowed. Any advice on which one is safer (less watched) to obtain would also be appreciated. I can`t wait to try the synthesis in...

Hi Patton, what do you do with the solvent (petroleum ether) after extracting the free base? Do you evaporate it until it is very small amount and then add EtOH? Can IPA be used as well? (Just because EtOH can be difficult to dry - or is dryness not a requirement at that stage?) When the...

There is link above to an Erowid page where a water free extraction is described which can be used when a medication contains PEG. It recommends to start with a non-polar solvent such as Xylene or Toluene and soak the powder for at least 6 hours (for PEG), I guess in this time the PEG dissolves...

Hi, I have found an over the counter product containing Pseudo + Ibuprofen in a gel capsule. First it seemed easy to extract as the substances are already in solution, Ibuprofen is only soluble in water when basis, so the opposite of pseudo. When I looked at the detailed ingredients, however, it...

Hi, is there anyone who knows the answer to the previous question? I have been thinking of the same thing, as I2 is readily available, so not clear what the advantage of using HI is. Is the yield better?

In my experience it is best to start the reaction when the amalgamation is started. Wait for a `sizzling` sound of the amalgam (Al + HgCl2 + water) and for all the Al coming to the top and small bubbles appearing. When all 3 signs are together 1.sizzling sound 2. Al coming to the surface...

Mr Patton, if you hear this, please tell us whether a Raman could identify Mercury nitrate from the end product?

Because the risk of poisoning is way higher during the synthesis when handling toxic mercury salts than when consuming the final product. Aluminium amalgam is very reactive and is already changed into mercury at the end of the synthesis. Elemental mercury is not too toxic when ingested orally...

Hi Patton, when you used 6g of the Amphetamine sulphate in the above extraction and then added half of the amount of D-Tartaric acid (in terms of mol). I think 3.3g is too much because when calculating the molar amount the freebase needs to be taken into account. 6g of Amphetamine sulphate is...

Sulphate contains more amphetamine by weight than phosphate, because the phosphate molecule is larger (bigger proportion of the amphetamine salt). So if you take equal amounts say 100mg of each then the Sulphate should be stronger. Some people also say that Sulphate absorbs/kicks in faster on...

thank you
