Buy BK-EBDP Powder

Buy BK-EBDP Powder (also known as N-Ethylpentylone , βk-EBDP, and ephylone) is a novel stimulantentactogen substance of the cathinone class. Ephylone is chemically related to pentylone and belongs to a group of compounds known as the substituted cathinones. Little is known about its pharmacology, although it likely produces its effects by increasing levels of serotonin, dopamine, and norepinephrine in the brain.

Ephylone was developed in the 1960s by Boehringer Ingelheim as a central nervous system stimulant, although it never became marketed. Reports of recreational use first appeared in late 2015. Since then, its prevalence has steadily risen, particularly at dance music festivals where it appears as an adulterant or counterfeit for MDMA. Ephylone has been linked to numerous hospitalizations and overdose deaths.

User reports indicate that ephylone produces a mixture of classic stimulant and entactogenic effects resembling those of MDMA, methylone and cocaine. Typical effects include stimulation, disinhibition, increased libido, compulsive redosing, and euphoria. Unlike similar substances, however, ephylone is reported to be very long lasting when taken in larger doses. The significance of this is not known, although it may indicate that it has a different toxicity profile compared to other stimulants.

Ephylone is sold online as a research chemical alongside other synthetic cathinones like ethylone and dibutylone. Due to the lack of research, it is highly advised to use harm reduction practices if using this substance.


Ephylone, or N-ethylpentylone, is a synthetic substance belonging to a group known as substituted cathinones. Substituted cathinones are derivatives of the naturally occurring substance cathinone, which is one of the psychoactive principles in khat (Catha edullis). Cathinone is composed of a phenethylamine core with an alkyl group attached to the alpha carbon, and a ketone group attached to the beta carbon.

Ephylone is a structural analog of pentylone. Pentylone’s chemical structure consists of a cathinone core substituted with a methylenedioxy ring at R3 and R4 of the phenyl ring, a propyl group at the alpha carbon, and a methyl group at the amino group. Ephylone has an identical structure with the exception of an N-ethyl alkyl substituting for the N-methyl moiety.


Very little data exists on the human pharmacokinetics and pharmacodynamics of ethylone and other substituted cathinones. Like amphetamines, synthetic cathinones exert their stimulating and sympathomimetic effects via increasing synaptic concentration of catecholamines such as dopamine, serotonin and norepinephrine. These molecules are able to inhibit monoamine reuptake transporters producing a decreased clearance of the neurotransmitters from the synapse. Furthermore, they may cause release of biogenic amines from intracellular stores.

Synthetic cathinones are generally less able than amphetamines to cross the blood–brain barrier because the beta-keto group causes an increase in polarity. Unlike other synthetic cathinones, pyrrolidine derivatives have a higher ability to cross the blood–brain barrier because the pyrrolidine ring confers a low polarity to these molecules. The studies on the metabolism of synthetic cathinones have shown that they are N-demethylated, the keto group is reduced to hydroxyl and ring alkyl groups are oxidised.

Subjective effects

Compared to other stimulant-entactogens, ephylone is reported to be more stimulating than entactogenic. Entactogenic feelings are said to be weak compared to substances like MDMA, 6-APB or methylone. Ephylone is also described as less euphoric and satisfying than traditional entactogens. Reports suggest that the physical side effects increase disproportionately to the desirable effects, which may promote compulsive redosing.

The effects listed below are based on the subjective effect index, which is based on anecdotal reports and the personal experiences of PsychonautWiki contributors. As a result, they should be treated with a healthy amount of skepticism. It is worth noting that these effects will rarely (if ever) occur all at once but heavier doses will increase the chances of inducing a full range of effects. Likewise, adverse effects become much more likely on higher doses and may include serious injury or death.

WARNING: Always start with lower doses due to differences between individual body weight, tolerance, metabolism, and personal sensitivity.
