Responsible Research with 3-FEA

Always practice responsible research. You should read and educate yourself before undertaking research with any chemical. The Psychonaut Wiki has some very helpful resources and information on 3-FEA.

What is 3-FEA?

3-Fluoroethamphetamine (also known as 3-FEA) is a novel ring-substituted amphetamine compound that produces a mixture of entactogenic and stimulant effects when administered. 3-FEA is structurally related to a series of designer fluorinated substituted amphetamines that originally included compounds such as 2-FA, 2-FMA, 3-FA, 4-FMA, 4-FA.

Like its parent compound 3-FA, the pharmacological, toxicological, and subjective effects of 3-FEA in humans have yet to be mapped out in detail. Anecdotal reports have characterised 3-FEA as a moderately potent serotonin-dominant triple monoamine releaser that produces a mixture of entactogenic and mild stimulating effects.

3-FEA has an extremely short history of human recreational use. Due to its potent psychostimulant effects, likely habit-forming properties, and unknown toxicity profile, it is strongly recommended that one use proper harm reduction practices if using this substance.

Chemical Properties

3-FEA, or 3-fluoroethamphetamine, is a synthetic molecule of the amphetamine chemical class. Molecules of the amphetamine class contain a phenethylamine core comprised of a phenyl ring bound to an amino (NH2) group through an ethyl chain substituted with a methyl group at Rα (i.e. amphetamines are alpha-methylated phenethylamines).

3-FEA is the 3-position fluorinated analog of ethylamphetamine (also known as ethamphetamine). It is also an analog of fenfluramine with the 3-trifluoromethyl group replaced with a 3-fluoro substituent.

Pharmacological effects

Although 3-FEA has not been formally studied on the same level as traditional amphetamines, it is currently assumed that like other substituted amphetamines with substitutions at similar positions, it most likely acts primarily as a triple reuptake inhibitor and/or releaser of the monoamine neurotransmitters serotonin, dopamine, and norepinephrine.

It has been demonstrated that compared to the unsubstituted ethylamphetamine, 3-fluoroethamphetamine is a weaker releaser of dopamine, but a stronger releaser of both serotonin and norepinephrine, producing the strongest reinforcing effects in animal studies out of a range of 3-substituted amphetamine derivatives tested, despite not being the most potent dopamine releaser.

This indicates that 3-FEA effectively increases the levels of all the three major monoamine neurotransmitters dopamine, norepinephrine, and serotonin in the brain by acting as a releasing agent of said neurotransmitters and/or by binding to and partially blocking the transporter proteins that normally clear those molecules from the synaptic cleft after they have fulfilled their function of conducting a neural impulse. This transporter blockade allows these molecules to accumulate within core synaptic regions of the brain to extra-endogenous levels, resulting in a combination of relaxing, stimulating, disinhibiting and euphoric effects associated with entactogenic substituted amphetamines such as MDMA or 4-FA.

Some of the most commonly reported effects are:.

  • Sedation & Stimulation
  • Perception of bodily heaviness
  • Spontaneous bodily sensations
  • Physical euphoria
  • Tactile enhancement

Some of the potential side-effects include:

  • Abnormal heartbeat
  • Increased heart rate
  • Increased blood pressure
  • Increased perspiration
  • Temperature regulation suppression
  • Headaches
  • Vasoconstriction
  • Dehydration
  • Dry mouth
  • Difficulty urinating
  • Appetite suppression
  • Pupil dilation
  • Teeth grinding
  • Diarrhea


3-FEA is classified as illegal in:

  • Austria
  • Canada
  • Germany
  • New Zealand
  • Switzerland
  • United Kingdom

This list is not exhaustive, so do your own research into the legal status in your country before ordering!

    Velmi kvalitní produkt. Funguje lépe než jsem čekal. Nebudu váhat a objednám znovu.

  2. Stef1 (verified owner)

    Very good product on and off, very good, thank you !

  3. Stef1 (verified owner)

    Pretty nice

  4. v0lkanbalci (verified owner)

    it’s a great chem, under 100-150mg the comedown is very forgiving compared to 6-apb and 5-mapb, 3-FEA also is very affordable, rats loved it, make sure the rats follow the same rules as they would with xtc.

  5. Skytrix (verified owner)

    4 fmph grande o 3 fpm meno forte ma buona poi sostituita da una merda tossica di 3 cpm << buttato via 5 grammi nel cesso. 3 fea ha un buon risultato stim sostenibile via orale e integrabile con altre sostanze empatogene ipnotiche senza nessun down finale, quindi 3fea è al momento la mia preferita, con le dovute sospensioni 😉 Grazie

  6. Tula (verified owner)

    Odporúčam ! preferujem orálne !

  7. Decak (verified owner)

    Its simmilar to MDMA. Dont use really high dosage its bad for your hearth
    Nice high and great euphoria. Nasal usage is really painfull. Prefer oral usage

  8. Paprikas (verified owner)

    Already tried 3Phoria, so I assume this will be similar if not a bit better. There was some misunderstading with this order which was promptly corrected by Team. Thank you (especially Jessica 🙂 )

    ressemble sur différent point à la 3mmc, la prise nasale est assez surprenante puisque elle tapisse la gorge. Le produit est en pate il faut donc le faire sécher un peu avant utilisation (la pate est cage de la fraicheur du produit). Dans mes expériences j’ai mélangé ce produit avec de la méthamphétamines, les deux ensemble sont une réelle expérience (je ne le recomande par forcement pour votre corp cependant). Le craving n’est pas forcement très important même si une réelle montée n’est pas la, on est plus directement sur le plateau après la prise. Ca peut être frustrant mais ca reste tout de même très intéressant par rapport au prix et les effets sont vraiment simpa. Pour moi c’est de la 3 mmc sans produit de coupe déguelasse et sans un effet mental autant accentué que avec de la 3 mmc. La 3 FEA augmente le rythme cardiaque, la taille des pupilles et peut faire crincer des dents comme tous les stimulants. Je ne dis pas que vous aller adorer ce produit mais je pense qu’il mérite d’etre gouter par tous les adepte de stimulants. Soyez tout de meme RDR essayez de faire un test allergique avant et buvez beaucoup d’eau pendant vos expériences. Le sérieux du site est encore une fois prouvé pour ma part.

    Amazing body high, music heaven, great for talking

  11. Esko. (verified owner)

    nice product

  12. Jony

    Good entactogen.

  13. spritzzzz (verified owner)

    pretty good but weird and “tired” rolls, but i liked them. One BIG problem: as a coke user i stronlgy discourage this rc as it provoked both times a very painful rectal ascess. For sure cocaine had its part but in the period of time from december to now this health problem showed up only in the 2 occasions i had used this rc meanwhile i had used coke almost weekly.

  14. Akiradz

    super prod, tester a 190mg et grosse stimulation et euphorie.

  15. Shulg (verified owner)

    Above 100mg the compound is very serotononergic, but not really energic. This is a mellow and almost sedative roll. Euphoria is very short lasting and the effects not that interesting or amazing.
    Only advantage is that the product is cheap.
    Not the best Fluoroampheth at all
    You should better source some 2-FA and 3-FA in place.
    Those are far more better ones.

  16. Smugler (verified owner)

    Nice Quality, also team behind that is awesome, after trouble with shipping i got 100% reship:)

  17. Koriace (verified owner)

    Test en laboratoire très concluant… Grandes stimulations !!!
    Reçu en France en 4 jours… Merci a vous 👍👍👍👍👍

  18. Gidolcet420 (verified owner)

    Great stimulant,and very cheap, will buy it again

  19. Nilhuse721 (verified owner)

    Don’t insuflate x) beginners mistake ! Otherwise quality is perfect as usual, been fresh since 2 month i bought it 🙂 respect for quality

  20. Rosco Jenkins (verified owner)

    Not the strongest stimulant like above but it certainly gives the kinds of results worth testing repeatedly.

  21. cbusiness1997 (verified owner)

    Not as much of a stimulant as something like 3-FPM, but the tests have been very positive!

  22. ChickenCobra (verified owner)

    This is a fantastically unique material. Tested Great!
