4-FMA Powder

Starting from €25.00


4-Fluoromethamphetamine, or 4-FMA, is a stimulant drug. As the name suggests, it’s a member of the amphetamine class of drugs closely related to both methamphetamine and 4-FA. Because of its similarity to these compounds there has been some controversy surrounding the use of 4-FMA.

  How to use 4-FMA powder 4-FMA has become increasingly popular since its discovery in 2006, although whether or not this is because of increased demand is up for debate. In 2018, a large number of 4-FA studies contained 4-FMA or other fluorinated amphetamines, indicating that certain vendors are cutting other products with 4-FMA. In addition to this, the availability of actual 4-FA has started to decrease. Fortunately we are not going to try to sell you anything besides what we are describing here: real, pure 4-FMA. Buy 4-FMA in the highest quality powder form. Buy 4-FMA in the quantities 1g, 2g, or 5g. Ensure to store the 4-FMA powder in a dry and cool place for maximum shelf-life. When handling research chemicals ensure to always take the proper precautions in the laboratory like wiping down surfaces and wearing gloves, a mask & protective clothing. 4-FMA is known to be a CYP450 inhibitor. This can cause an interaction between other chemicals that are being researched at the same time. If you are researching 4-FMA then you should do so separately from other compounds as this can cause unpredictability and potentially put you at risk.   Definition 4-FMA The definition of 4-FMA is officially known as 4-fluoromethamphetamine, is a substituted amphetamine.  Substituted amphetamines are compounds that are known to share similarities in their pharmacological action. Substances in this class are generally acknowledged as being stimulants, and 4-FMA is no exception. 4-FMA is also speculated to possess entactogen properties. Many researchers report that their studies on 4-FMA have placed it somewhere between 4-FA and 2-FMA. If you have experience working with either of these compounds then you may be well-equipped to experiment with 4-FMA. However, researchers also report that the compound is a bit more volatile. Proper care must be taken when using any compounds in the amphetamine class to minimize unwanted results.    Chemistry background information 4-FMA Substances in this chemical family have a base phenethylamine core with a phenyl ring attached to an amino group via an ethyl chain featuring an additional methyl substitution. In fact, this is what gives rise to the name amphetamine, which is a shortened version of alpha-methylphenethylamine.  This particular molecule, 4-FMA, has a fluorine atom at the R4 space on its phenyl ring. This makes it a fluorinated analog of methamphetamine. As such, researchers can expect it to share a number of similarities with this amphetamine as well as other substances in this category. There is limited pharmacological data regarding the use of 4-FMA, although it is speculated to operate in a similar manner as other stimulants in the same class. These substances exhibit dopaminergic and serotonergic properties.   Where to buy 4-FMA 4-FMA can be purchased here on the Realchems website. We sell premium quality 4-FMA, typically in powder.
