u-47700 / u 47700 buy

u-47700 / u 47700 buy . U-47700, also known as pink heroinpinky, and pink, is an opioid analgesic drug developed by a team at Upjohn in the 1970s[1] which has around 7.5 times the potency of morphine in animal models.

Physical Sample of u-47700 / u 47700 buy

u-47700 / u 47700 buy is a structural isomer of the earlier opioid AH-7921[6] and the result of a great deal of work elucidating the quantitative structure–activity relationship of the scaffold. Upjohn looked for the key moieties which gave the greatest activity[7] and posted over a dozen patents on related compounds, each optimizing one moiety[8][9][10][11][12][13][14][15] until they discovered that U-47700 was the most active.[16]

U-47700 became the lead compound of selective kappa-opioid receptor ligands such as U-50488, U-51754 (containing a single methylene spacer difference) and U-69,593, which share very similar structures.[17][18] Although not used medically, the selective kappa ligands are used in research.

Side effects Of u-47700 / u 47700 buy
U-47700 has never been studied on humans, but would be expected to produce effects similar to those of other potent opioid agonists, including strong analgesia, sedation, euphoria, constipation, itching and respiratory depression which could be harmful or fatal. Tachycardia was another side effect encountered with U-47700 use. Tolerance and dependence would be expected to develop.[29]

Combined consumption of U-47700 with fentanyl and flubromazepam caused one fatality in Belgium and Germany, respectively. One death was reported in Ireland,[33] another one in Italy.[34] 17 opioid overdoses and several deaths in the United States had initially been associated with U-47700 in April 2016,[35] as of September 2016 at least 15 fatalities were confirmed. By December 2017, at least 46 fatalities had been associated with the use of U-47700.

u-47700 / u 47700 buy was found in combination with fentanyl during the autopsy of the American artist Prince in 2016.

Detection in biological fluids
u-47700 / u 47700 buy . U-47700 may be measured in serum, plasma, blood or urine to monitor for abuse, confirm a diagnosis of poisoning, or assist in a medicolegal death investigation. Serum or blood U-47700 concentrations are expected to be in a range of 10–250 μg/L in intoxicated patients and 100-1500 μg/L in deceased victims of acute overdosage. The detection usually involves analysis by liquid chromatography-mass spectrometry
