Best method to manufacture Methamphetamine in large scale

[wadekaiak]

Hello, what would be the be the most cost efficient method to manufacture around 1kg of Methamphetamine. I don't care wether it's racemic or not.

Regarding the ephedrine / pseudoephedrine method, for every 1 kg of ANY of those substances, how much Meth would I be able to get?

I can get both pseudoephedrine and ephedrine pretty easily around here, altough its very expensive. I don't know if it would be worth.

Which other methods could be viable in order to produce a 1kg batch with not so hard precursors?

Is P2P too difficult to obtain? Is it worth it?

Thanks in advance!

In the insightful words of our predecessors, use the fucking search engine
Really though 50-80% is what I'm seeing from ephedrine enantiomers. P2P I saw a 65% so it's in the same range. Phenylcarbonal phenylpropanolamine L-pac, P2NP, phenylacetone, benzyl chloride and a few other things are 2-3 steps away.
If it's all the same to you, L-ephedrine or D- pseudoephedrine make D-meth, which is worth a lot more money than D,L

P2P (aka BMK) can be bought as a glycidate ester from China and converting the p2p glycidate to p2p is trivial.
