3-Fluoroamphetamine (3-FA) is a synthetic amphetamine derivative, incorporating a fluorine substitution on the amphetamine ring structure. This compound is renowned for its potent classical stimulant properties, often being described as nearly as powerful as methamphetamine[^1^]. It belongs to a family of designer amphetamines that feature fluorine substitutions, including 2-FA, 2-FMA, 3-FEA, and 4-FA. These compounds are notable for their ability to induce euphoria and stimulation, gaining popularity as research chemical alternatives to traditional street stimulants.
It’s important to note that 3-FA is seldom encountered in street drug markets, with limited availability. Instead, it occasionally appears within the grey market as a research chemical, primarily distributed through online vendors. This little street presence, coupled with its classification as a research chemical, places it in a unique and evolving niche within the broader stimulant landscape. Researchers and individuals interested in these substances should exercise caution and stay informed about changing legal and safety considerations.

3-Fluoroamphetamine, often referred to as 3-FA, belongs to the amphetamine class of synthetic molecules. Amphetamines share a standard phenethylamine structure, characterized by a phenyl ring linked to an amino (NH2) group through an ethyl chain, and typically, they possess an additional methyl substitution at the Rα position (meaning they are alpha-methylated phenethylamines). Notably, 3-FA lacks the methyl group attached to the terminal amine RN of the amphetamine core, making it structurally and functionally akin to amphetamine itself. In essence, 3-FA can be regarded as the 3-fluorinated counterpart of amphetamine.


While formal research on 3-FA has not reached the same depth as traditional amphetamines, it’s reasonable to hypothesize that, like other substituted amphetamines with similar structural modifications (with the notable exception of 4-FA), it likely primarily functions as a dopamine and norepinephrine-releasing agent. Additionally, it may exhibit moderate selectivity for serotonin. This means that 3-FA is likely to enhance the levels of dopamine and norepinephrine neurotransmitters within the brain. It achieves this by binding to and partially obstructing the transporter proteins responsible for clearing and reuptaking these molecules from the synaptic cleft, where they are released during neural signaling. Consequently, dopamine and norepinephrine can accumulate in the brain to levels beyond what the body naturally produces. This accumulation is known to have stimulating, motivating, and euphoric effects in humans.

Subjective effects

3-FA is acknowledged as a potent and multifaceted stimulant, distinguishing itself from other substances in its class, such as 4-FA, by offering mild entactogenic qualities. However, it needs to exhibit the productivity and focus-enhancing attributes commonly associated with 2-FA or 2-FMA, which has somewhat limited its appeal.

Please note that the effects detailed below are drawn from the Subjective Effect Index (SEI), a compilation of anecdotal user experiences and analyses by contributors to PsychonautWiki. Consequently, these effects should be approached with a degree of skepticism.

It’s crucial to understand that these effects may not manifest predictably or consistently, and higher doses are more likely to encompass the full range of products. Additionally, escalating doses increase the likelihood of adverse consequences, including the potential for addiction, severe harm, or even fatality ☠.


  • Stimulation
  • Tactile enhancement (typically more pronounced at higher doses)
  • Physical euphoria
  • Dehydration
  • Appetite suppression
  • Increased heart rate
  • Increased perspiration
  • Teeth grinding (comparatively less intense than MDMA or 2-FMA)


  • The post-stimulant phase, often termed a “comedown,” is typically characterized by negative and uncomfortable sensations due to neurotransmitter depletion. It may include:
    • Anxiety
    • Cognitive fatigue
    • Depression
    • Irritability
    • Suppressed motivation
    • Slowed thought processes
    • Wakefulness


  • Cognitive euphoria
  • Accelerated thought processes
  • Enhanced focus
  • Anxiety alleviation
  • Heightened wakefulness
  • Improved analytical abilities
  • Increased motivation
  • Compulsive redosing
  • Enhanced music appreciation (more evident at higher doses, as lower to medium quantities tend to be productivity-focused)
  • Time distortion, involving the perception of time passing faster than usual when sober


Below is a revised list of potentially dangerous interactions with substances, although it may not cover all possible interactions. Always conduct thorough independent research (e.g., using Google, DuckDuckGo, PubMed) to ensure the safety of combining two or more substances. Some of these interactions have been sourced from TripSit:

  1. Alcohol: Combining alcohol with stimulants is risky because it diminishes the sedative effects of alcohol that typically help gauge drunkenness. This can lead to excessive drinking, reduced inhibitions, and an increased risk of liver damage and dehydration. Stimulants can also mask the usual signs of alcohol intoxication, potentially allowing one to consume dangerous amounts.
  2. GHB/GBL: Stimulants increase respiration rates, potentially allowing for higher doses of sedatives. If the stimulant wears off before the depressant effects of GHB/GBL, it may lead to respiratory arrest.
  3. Opioids: Stimulants can also increase respiration rates, potentially permitting higher doses of opioids. If the stimulant’s effects wear off before the opioids, it could lead to respiratory arrest.
  4. Cocaine: Combining amphetamines with cocaine can lead to cardiac effects due to interactions with serotonin receptors. This combination may increase the risk of heart issues, including valvulopathy, hypertension, and syncope.
  5. Cannabis: Stimulants can raise anxiety levels and increase the risk of thought loops and paranoia when combined with cannabis, potentially leading to negative experiences.
  6. Caffeine: Combining stimulants like caffeine and other stimulants may be unnecessary and can strain the heart, potentially causing anxiety and physical discomfort.
  7. Tramadol: Both tramadol and stimulants increase the risk of seizures when combined.
  8. DXM: Both substances raise heart rate, potentially leading to panic attacks and more severe heart issues in extreme cases.
  9. Ketamine: Combining amphetamines and ketamine may result in psychoses resembling schizophrenia, mainly due to interactions in the dopaminergic pathways. This combination can lead to thought disorders and positive symptoms.
  10. PCP: Combining stimulants with PCP can increase the risk of tachycardia, hypertension, and manic states.
  11. Methoxetamine: Mixing stimulants with methoxetamine can increase the risk of tachycardia, hypertension, and manic states.
  12. Psychedelics (e.g., LSD, mescaline, psilocybin): Combining stimulants with psychedelics can heighten the risk of anxiety, paranoia, and thought loops.
  13. 25x-NBOMe: The stimulation from amphetamines and NBOMes can result in tachycardia, hypertension, vasoconstriction, and, in extreme cases, heart failure when combined. The anxiogenic effects of stimulants can also exacerbate thought loops.
  14. 2C-T-x and 5-MeO-xxT: These substances may have mild MAOI properties, potentially increasing the risk of hypertensive crisis when combined with amphetamines.
  15. DOx: Interaction risks exist with DOx compounds, although specific details may vary.
  16. aMT: aMT has MAOI properties, which could interact unfavorably with amphetamines.
  17. MAOIs: MAO-B inhibitors can enhance the potency and duration of phenethylamines unpredictably, while MAO-A inhibitors combined with amphetamines can lead to hypertensive crises.
