AP-238 is an opioid analgesic drug that was widely used in China to treat pain in cancer patients as of 1986. It is one of the most potent compounds among a series of analgesic acyl piperazine compounds first synthesized and reported in Japan in the 1970s. AP-238 has analgesic potency 4-5times of morphine but with a relatively higher therapeutic index. The drug was initially claimed to be a non-narcotic analgesic. However, subsequent studies have shown bucinnazine and similar acyl piperazines to be potent and selective agonists of μ-opioid receptor (MOR) with relatively low affinity for the δ-opioid receptor and the κ-opioid receptor. In accordance with these studies, results from the intravenous self-administration experiments in rats showed that ap-238 has a marked reinforcing effect with tolerance and dependence quickly developing In addition, the morphine antagonist naloxone reverses the effect of ap-238 and precipitates withdrawal symptoms in ap-238 treated rats further indicating a mechanism of analgesia mediated via selective agonist activity at μ-opioid receptors.

Great information, kinda hard to find this one. I did ordered some, we'll see how it goes.

The information are correct, except AP-238 is a made-up name. But the structure has been revealed. It's an AP237 analogue/derivate. Still, it's true the currently potency SHOULD be 4-5x, If it will be euphoric or purely sedative, we'll know in a few days.

Any update/reports about AP238?

I'll probably grab some at one point or another but duration just looks so disappointing. 237 was/is such a tease to me and this doesn't seem much better, hah
