4-FMA Powder

Brief Intro

4-FMA Powder (4-Fluoromethamphetamine) is a synthetic stimulant and entactogen belonging to the substituted amphetamine class. Structurally related to methamphetamine and 4-fluoroamphetamine (4-FA), 4-FMA is known for its amphetamine-like stimulating and mood-enhancing effects. It has been sold as a designer drug and is primarily used in scientific and forensic research to study its pharmacology, metabolism, and toxicological profile. This compound is strictly intended for research purposes and is not for human consumption.

Pharmacology and Mechanism of Action

4-FMA acts as a releasing agent and reuptake inhibitor for dopamine, serotonin, and norepinephrine, leading to stimulating and entactogenic effects. At lower doses, it produces amphetamine-like stimulation, while higher doses yield more pronounced euphoria and empathogenic effects similar to MDA. 4-FMA inhibits cytochrome P450 enzymes (notably CYP2D6, CYP3A4, and CYP2E1), which can influence both its own metabolism and that of other substances. It has been shown to destabilize mitochondrial membrane potential, reduce ATP levels, increase production of reactive oxygen and nitrogen species, and compromise antioxidant defenses in liver cells. These actions contribute to its recognized hepatotoxic potential and unpredictable toxicity profile.

Intended Use

4-FMA Powder is intended strictly for laboratory research, forensic analysis, and toxicological studies related to synthetic stimulants, substituted amphetamines, and novel psychoactive substances. It is not for human or veterinary consumption.
