Its all true, but one. There are very educated and experienced people that can do it in a larger home lab (at a farm), and I know some of those chemists. He did though stipulate: > MOST people can't do it And I would even say MOST modern 2021 lower-standards college chemistry grads with just a BS and a normal range IQ can't do it properly, to my definition of "proper" Even after synthesis and a pathetic yield (to ensure utmost purity), you need to wait 2 weeks for your toxicity studies of the batch in small mammals, including a sad LD-50 threshold test for an unfortunate rat. This chemical is forgiving and is non deadly up to 250x the normal dosage, so the LD-50 is for unknown byproduct revelation of your batch, and unknown purity of your batch. 250x cited : https://pubmed.ncbi.nlm.nih.gov/17234315/ He is right that no expert will hand a "loaded gun" to a uneducated novice, and will not cherry pick a "easy" old patent with a low yield that would be best for a home lab.
