Buy Fentanyl Powder

Buy Fentanyl Powder, also spelled fentanil, is an opioid used as a pain medication and together with other medications for anesthesia. Fentanyl is also used as a recreational drug, often mixed with heroin or cocaine. It has a rapid onset and effects generally last less than two hours. Medically, fentanyl is used by injection, as a patch on the skin, as a nasal spray, or in the mouth.

Common side effects include vomiting, constipation, sedation, confusion, hallucinations, and injuries related to poor coordination. Serious side effects may include decreased breathing (respiratory depression), serotonin syndrome, low blood pressure, addiction, or coma. Fentanyl works primarily by activating μ-opioid receptors. It is around 100 times stronger than morphine, and some analogues such as carfentanil are around 10,000 times stronger.

Fentanyl was first made by Paul Janssen in 1960 and approved for medical use in the United States in 1968. In 2015, 1,600 kilograms (3,500 lb) were used in healthcare globally. As of 2017, fentanyl was the most widely used synthetic opioid in medicine. Fentanyl patches for cancer pain are on the WHO List of Essential Medicines, which lists the most effective and safe medicines needed in a health system.


Fentanyl provides some of the effects typical of other opioids through its agonism of the opioid receptors. As a Mu-receptor agonist, it binds 50 to 100 times more strongly than morphine. Fentanyl can also bind to the delta and kappa opioid receptors but with a lower affinity. Its strong potency relative to morphine is largely due to its high lipophilicity, per the Meyer-Overton correlation. Because of this, it can more easily penetrate the central nervous system.

Fentanyl binds to opioid receptors⁠ ⁠— G-protein coupled receptors (GPCR) which regulate synaptic transmission. Binding of fentanyl activates the GPCR which initiates signalling to result in the inhibition of the release of nociceptive neurotransmitters. This inhibits the ascending pathways in the central nervous system to increase pain threshold by changing the perception of pain; this is mediated by decreasing propagation of nociceptive signals, resulting in analgesic effects.


The use of fentanyl in execution caused concern among death penalty experts because it was part of a previously untested drug cocktail. The execution was also protested by anti-death penalty advocates at the prison during the execution and later at the Nebraska capitol building.
