...it's really hard to predict what will happen if this ban is enforced. The market might get shaken up a bit, reputable raw suppliers products might see a cost increase for consumers, same for reputable suppliers, new companies might pop up...some legit and some bunk, product quality may take a hit, and manufacturers and distributors may change causing a temporary lapse in availability
...the possibilities are many but they may create an environment more conducive to shifting the AAS business from more of "a buyers market" to "a sellers market"...this would be unfortunate for all of us but I don't believe that those who make their livelihood in China off of AAS will close up their large scale operations and go home.
@Kindlife is correct in stating that all businesses in China must pay a portion of their profits to the Chinese government to do business. Whether being licensed with the government is the issue or not I wouldn't be able to say...
...however...
Last I read about the production of Fentanyl in China, it worked like this over there:
Fentanyl production is banned in China...their chemists their create a new analogue of Fentanyl...that analogue is banned...chemists create another analog of Fentanyl...that analogue is banned...chemists create a new analogue...and so on...
In the U.S., Fentanyl, already created analogs of Fentanyl, and every future yet to be created analog of Fentanyl are already banned.
China could do this if they wanted...but they don't. Business is business for them and as long as it isn't poisoning their population, they don't really care much.
While creating new steroid analogs is highly unlikely, I believe that this new law in China is probably only going to be a temporary issue as far as we consumers are concerned...I could be wrong but I don't believe there's much incentive for the U.S. to put enough pressure on China to abandon the steroid industry when the vast majority Fentanyl is definitely still coming from China.
...on the other hand...who knows...maybe this will be a meaningless feather in the president's hat to brag about to the people in light of more pressing U.S. issues.
...look at the upcoming SARMS bill being brought to legislation right now which is attempting to make them schedule III officially.
