Just a quick comment without having to resort to naming vendors/price, etc.
Chinese labs are more than capable of producing LSD and/or analogues. We aren't talking about run of the mill garage chemistry, we are talking about industrial production facilities that can turn an entire shift over to the production of one chemical. Most of the chemicals we order at work source from China (most of the biologicals come from North America/Europe). Sometimes chemicals are available for immediate shipment (a chemical that is made and sold regularly, and present in high stock), others have a wait time of up to 30 days (they have to be synthesized, purified and characterized....typically IR, NMR, mass spec). Requirements for test data are made at the requirement of North American resellers. In other words, the chemical is made to their specification.
If a single lab requires a chemical, the cost is greater and so is the wait time if not in stock. You're paying for raw materials/chemicals/supplies personnel and equipment expense. Large, sophisticated chemical manufacturing complexes can easily do this. They've got the ability to test scale synthesize and manufacture in anhydrous, inert atmospheres.
The Chinese industrial reps I've met (for biologicals, not chemicals) give out free samples, emphasize the speed and cost of their productions and point out that they can dedicate their capacity to our needs.
Obviously I'm of the opinion that the Chinese can (and in my opinion have or will) produce(d) AL-LAD, LSZ and other analogues.
