Actual working P2NP to Amphetamine synthesis, high yield, 100-1000grams in scale?

[warmbid]

Could someone please advice me on the best route to amphetamine from P2NP, I'm finding lots of posts about high yield synths but then when I read the comments the instructions seem to not work for everyone.

Could someone share a method that is true and tested, as in that you've actually got an X amount of yield from yourself?

Would it maybe be better to convert to P2P? My end-goal is dextro-amphetamine. I would like to keep the lab-equipment as simple as possible if possible though.

Hope I can get some opinions!

Thanks in advance.

Are you sure about this one:

One Step Dextroamphetamine Synthesis

Introduction The method have developed for the manufacture of amphetamine, that avoids the use of bases, avoids the use of toxic and dangerous reagents, requires mild reaction conditions, produces essentially no by-products or impurities in the final products thereby eliminating the need for...

Because I've never heard of someone confirming / having success this way, it seems too good to be true also. yield also superb.

And are you sure on this one's yield? Most comments seem to not get close

You can write to the author of the original patent with such question:

I'm from BB Forum and I read your patent, It seems too good to be true. Probably, technical editorial office of the Patent Office is too silly to accept this work and make patent for u.
