The team also procured secondary ingredients used to process the essential precursors, as well as basic equipment – giving it everything needed to produce fentanyl.

The core precursors Reuters bought would have yielded enough fentanyl powder to make at least 3 million tablets, with a potential street value of $3 million – a conservative estimate based on prices cited by U.S. law enforcement agencies in published reports over the past six months.

The total cost of the chemicals and equipment Reuters purchased, paid mainly in Bitcoin: $3,607.18.

Turning these precursors into fentanyl would have required just modest lab skills and a basic grasp of chemistry. One Mexican fentanyl cook who dropped out of school at age 12 told Reuters he learned the trade as an apprentice at an illegal lab.

“It’s like making chicken soup,” said the cook, an independent producer based in the cartel stronghold of Sinaloa state. “It’s mega-easy making that drug.”

It’s like making chicken soup,” said the cook, an independent producer based in the cartel stronghold of Sinaloa state. “It’s mega-easy making that drug.”

They paid 3700 for everything needed, including the glassware. The article details it all, even the pill presses and new analogs that hadn't been discovered before, in the arms race against banning or restricting fentanyl precursors. The sellers themselves stated in the article exactly how to make the drug, including step by step guides, and chemical diagrams explaining the Gupta method.
