Look at the history of the US "cracking down" on drugs ... has it ever worked? Bottom line, there is too much money in the market to stop it. Even for the lower prices we are paying. Worse case scenario is that the government makes the process more annoying and it raises the prices.
Take semaglutide for example, it costs about $5 to create a month supply of the retail version and the majority of that cost is the packaging. That number includes a normal profit margin too.

OK, let's look at a Chinese vender price ... $65 from MIX ... that is at least a $55 profit. A kit of Tirz 60mg is $180 and a Reta 50mg is $310. They probably all cost about the same to make. If true, then a kit of each would bring a profit of $170 and $300 respectively. Now let's say there is a US based reseller making an order for 1000 kits of 50mg Reta ... a Chinese vender is going to want that stuff to be delivered come hell or high water. That delivery would be a box that measures less than 14 cubic feet. Visualize a box (or multiple boxes together) that is smaller than a refrigerator and weighs less than 50 pounds. Drug dogs aren't trained to smell it. Losing a shipment would cost $1000 but a successful shipment brings in $300,000. Heck even a successful shipment of lowly sema is $55,000 of profit.
So let's say the average single kit is a profit of $100 ... and we are each buying about 2-3 kits per year ... there are over a million of us just in the US. That alone is a 3 billion dollar per year industry. And I am being very conservative with the numbers. Considering that the average income in China is about $17,000 ... yeah, they aren't going to stop the supply. No matter how much a shithead senator cries about it.
