Summary
3-FPM is a functional stimulant related to phenmetrazine, producing effects similar to amphetamine with reportedly less nervousness and euphoria. Users describe it as more subtle and focused, making it suitable as a study aid. However, significant concerns exist: some users report serious flu-like symptoms on comedown (muscle aches, fever, chills) potentially due to systemic inflammation, and rare cases of severe adverse reactions including vasculitis have been documented.

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance to desirable effects builds rapidly within a day of repeated dosing and partially resets over 3–7 days; anecdotal reports suggest cross-tolerance with other stimulants. Data quality is low and based on community self-reports rather than controlled studies.

Three Trials With 3-FPM I work an office job which involves a lot of writing under tight deadlines. Often, my ADHD makes meeting those deadlines quite difficult. I've been interested in stimulants since being prescribed methylphenidate some years ago, and I'd read about 3-FPM before acquiring some from a reputable lab...
FIRST TIME TRYING 3FPM I recently received in the mail a small amount (1g) of 3-fluoro-phenmetrazine (3-FPM), which is legal (albeit in a grey area of legality) in my country and sold as a research chemical.
Experience: I'd say I'm a pretty experienced user. I like most psychedelics, empathogens and stims. Don't like Cannabis. Dissociatives and sedatives. Only use benzo's if it's important.
Background: Fairly inexperienced with classic/rc stimulants, some experience with psychs, empathogens. First time using insufflation as the main ROA. Tested upon receiving Previously done an 'allergy test' and a threshold oral dose (no noticeable effects) Set/Settting: Home alone with no set plans for the day.
DOSES: T+00:00 3-FPM 48 mg oral WHO I AM 45 year old male, around 210 lbs, experienced. I've tried and loved all the classic psychedelics (DMT, LSD, Mushrooms, Mescaline both from cactus and synthetic), many new classics (most 2C-x and DOx, MDMA), and several other widespread compounds (NBOMEs, Methylone, many 4-sub an...
So I received 250mg of this crystal/shard-like chemical this morning. Me and the girlfriend have been after a functional stimulant which is fairly cheap, and fits our criteria. This substance definitely does.
I have been on the RC scene since 2011 and have since stopped my tendency to 'get fucked up', everything from MXE to 25B-Nbome is under my belt. I am a healthy individual with no mental or physical illnesses. For stimulants, I have little experience, but I have insufflated much 'Speed' and 'Ritalin'.

So, me and my partner were planning a night on 3-FPM. We are taking this substance in aid of a sexual and naughty night as this is what the chemical does for us. We have a fair amount of experience in taking 3-FPM but have just documented our most recent experience with the chemical. Last night to be precise.
weight = 65kg addiction = none tolerance = high use of salbutamol for asthma give me physical tolerance to dopaminergic stimulant dose = 20 mg (scale, but my scale if not very precise with so low dose) T+000 : Dissolved in coca-cola, dissolve well. Taste is acceptable. Drink all my cola.
Other drugs/vitamins taken: 50 mg sertraline every other day 4 mg estradiol valerate every day vitamin A, C, E and selenium combo pill taken a few hours before. State at time of experience: On the tail end of a cold, but feeling mostly recovered from that.
20161104 Male: 30 years: 85 Kg (~187lb) A vendor mistakenly sent me 75 mg 3-FPM tablets instead of 10 mg 2C-B-FLY tablets. I'm going to try them now. I chop the pill up in 2 quarts and 1 half. 18:10 / T +0 I eat one quart. Should be somewhere around 15-20mg worth of 3-FPM.
