I have had only one experience prior to this with 3-FA. This previous experience involved a 54 mg insufflated dosage of 3-FA used as a booster on a 2-FMA initial dosage. This is my first attempt at oral administration with the substance.

Summary
3-FA is a potent stimulant with mild entactogenic properties. It releases dopamine at levels significantly higher than amphetamine at equivalent doses but lacks the productivity-enhancing effects of 2-FA or 2-FMA. The substance has an extremely limited research history and unknown long-term toxicity profile.

Acute tolerance to subjective and cardiovascular effects develops within a session; partial recovery occurs over several days with baseline typically returning within 1โ2 weeks if abstinent. Cross-tolerance with other amphetamines is expected due to shared transporter-mediated mechanisms.

Introduction IMPORTANT: If the chemical has activity below 50mg it is advisable to use a suitable, human-safe solvent and dose volumetrically, since many common milligram scales are not accurate below that amount. This report will be broken into two parts: initial dose and supplement.
Context: I take amphetamines mainly when I want to have a lot of fun writing or when Iยm desperate about a deadline. I had experience with D-amphetamine, 2-FA, 3-FA, 2-FMA, 3-FMA, Iยm able to recognize the subtle differences between them and have used all of them in this context at varying doses with 2 routes of admini...
