Buy U-47700 Online, nicknamed “U4,” “pink,” or “pinky,” is a highly potent synthetic opioid that looks like a white or light pink powder. A lot of times, it is often either sold in baggies or pressed into pills to look like legal painkillers.
U-47700 is an opioid analgesic drug developed by a team at Upjohn in the 1970s which has around 7.5 times the potency of morphine in animal models.
U-47700 is a structural isomer of the earlier opioid AH-7921 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 and posted over a dozen patents on related compounds, each optimizing one moiety until they discovered that U-47700 was the most active.
