Our raw materials are synthesized by large scale manufacturers and contract research organizations (CROs). Our manufacturers are primarily based in China. Some are based in Europe and America. This is for economic reasons, it is simply less expensive.
There is justifiable concern about non-Western manufacturers whose regulations are less strict, if not completely unenforced. The modern chemical manufacturing industry is dominated by China. It is highly likely any industrial, nutraceutical or pharmaceutical product you are working with was processed in China.
This is not a concern however as long as your vendor is conducting third party analysis. You should always demand evidence of third party analysis for your research supplies.
Our non-API materials are sourced domestically, including solvents, packaging and containers.
