Rapamycin/sirolimus status in China

I was asked what is rapamycin/sirolimus’ status in China. I know numerous Chinese companies are making/marketing sirolimus. Does anyone have information regarding purity and reliability? Also, are sirolimus tablets available in China? Is it a prescription drug in China? Is there a segment of the Chinese population that is interested in life extension therapies and products…???

Sirolimus as Rapamune is readily available through major Chinese online retailers. It is by prescription only but online prescription is easy to get. The price of Rapamune 10mg is around 30 USD, so no need for substitutes. There is a community of biohackers, still quite infantile but definitely growing.
