This product must be legal in the destination country, or we won’t accept the order. It is the customer’s responsibility to conduct the necessary research regarding their local laws. Below you find a map that shows how we see the current situation regarding the legality of 4cmc. Our law-research concluded that 4cmc is unregulated in Netherlands, Spain, Romania, Liechtenstein, Portugal, Slovenia, Estonia, Greece, Luxembourg, Republic of Serbia.
If you think this data is incorrect, please email us about it providing law-texts. We only ship to green areas. We are sure 4cmc is banned in the red areas. We don’t know about the grey/brown areas. If you want a shipment to such a country, please provide us your local law-texts, and we will change color to green after a positive check.

Product description

4CMC, also known as Clephedrone, is a stimulant drug of the cathinone class that has been sold online as a designer drug.


In radioligand binding assays, 4-CMC had very low affinities of 9,410 nM, 28,700 nM, and 19,600 nM for the dopamine transporter (DAT), serotonin transporter (SERT), and norepinephrine transporter (NET), respectively. In uptake potency assays, 4-CMC had low uptake potencies of 208 nM, 670 nM, and 75.5nM for the DAT, SERT, and NET, respectively. 4-CMC possessed full efficacy at stimulating the release of dopamine. The maximal response elicited by 4-CMC was 83.5% of the efficacy of methamphetamine. The maximal response elicited by 4-CMC was 124% of the maximal efficacy of methamphetamine. 4-CMC was more potent (EC50value = 1,980 nM) at stimulating release of serotonin compared to methamphetamine (27,500 nM).


In mouse locomotor activity assays, treatment with 2.5 to 10 mg/kg 4-CMC i.p. resulted in time-and dose-dependent increases in locomotion. Peak locomotor effects were observed following 5 mg/kg 4-CMC. Maximal locomotor stimulant effects of 5 mg/kg 4-CMC occurred 10-40 min post injection and lasted 70-230 min. Compared to cocaine, methamphetamine, and MDMA, the maximal stimulant effectsof 4-CMC were 66%, 63% and 64%, respectively. In drug discrimination assays, 4-CMC i.p. fully substituted (ED50= 4.3mg/kg) for the discriminative stimulus effects of 10 mg/kg, i.p. cocaine in rats. 4-CMC also fully substituted (ED50= 3.9mg/kg) for the discriminative stimulus effects of 1.0mg/kg, i.p.(+)-methamphetamine.


We make 4CMC at our own lab. Crystals are transparent and huge, see image below. It has a purity over 99%. Please store sealed. For long term storage keep at -20 degree. Durability is 7 years.
