4-fa reagent testing

I came across some pills that are supposed to be 4-fa. They are orange pills that have b974 on one side and 30 on another, mimicking Adderall. I want to test them but I'm struggling to find out how 4-fa should react with reagents. I've also not been able to find any reports of 4-fa coming in tablets like these, though I did find reports of meth being sold like this.

Any advice on testing them?
 
Hey,

If I remember correctly, 4-FA is essentially extinct these days (someone please correct me if I’m mistaken). It seems unlikely that anyone would deliberately waste whatever small amount of 4-FA might still be in circulation just to replicate Adderall. I’ve never personally taken 4-FA, but from what I’ve read, it’s quite “rolly,” with typical doses ranging from 40–140 mg according to PsychonautWiki.

I’d strongly recommend sending a sample to Kykeon Analytics. They’re a lab based in Spain, and for just €20, you can get a clear, definitive analysis of what’s actually in those pills. I’ve used their services multiple times and can’t recommend them highly enough.

TL;DR: Send a sample to Kykeon Analytics for proper analysis.

To be clear, they were sold as 30mg 4fa. The product received, however, were tablets made to look like Adderall pills. It's from a reliable RC vendor that I've received other things from that were always high quality. I test everything regardless, and my gut feeling is that this is likely meth so I will 110% test them before any ingestion. I've been unable to find any other references to 4fa being sold in tablets like these, but plenty of meth sold this way. As you pointed out, typical doses of 4fa start at around 40mg and often go much higher. Oral meth starts much lower and 30mg is considered a strong dose of meth, so perhaps that's another context clue towards it being meth. The pill also has indents to break it into fours.

I was going to just do a reagent test but in this case I'd rather play it safe and send it to a proper lab. I bought these because 4fa is considered to be "MDMA lite" and I wanted something that could be used more often. I'm far too old to be taking pills without a pretty good idea of what's in them so I'm gonna test them.

I do hope that this is actually 4fa, less for the drug itself, and more because I've had a positive business relationship with this vendor for years and would hate to find them doing something so scummy as intentionally mislabeling product. The vendor does not sell meth or non-RC stims at all, so if this isn't 4fa, this couldn't have been an innocent mix up.

Luckily I only bought three tablets so if it turns out to be something else, I didn't lose much money.

As for the rarity of 4fa, I can say I've seen many listings for it from US based vendors. Of course, it's possible the majority of these are fake.

Thanks.

Please let me know the results when you reagent test it or send it to a lab. I’d bet good money it’s probably just meth for the reasons already stated, but idiots with pill presses have done stranger things. Like anyone, I’d be skeptical. I’d expect 4-FA to be pressed into an unmarked pill or sold as raw powder.

If it really is 4-FA, then you’ve stumbled onto something that we will probably never see again in our lifetime. I picked up some 2C-E (not a fan), 2C-I, clonazolam, and 4F-MPH a few months back, so that kind of stuff is definitely still floating around. Still, it’s very strange that something which was quasi-legal in parts of Europe would be branded as Adderall. I’d imagine it stops being in any sort of grey area the moment they cross that line.

I'll most likely perform a reagent test by the 23rd, and may send it off for a proper analysis.
I will update as soon as I do it.

Its highly suspect but I'm still holding out hope.
 
It is most likely meth, though it may be 4-FMA as the orange dye in the tablets can obscure the frohde reaction.

I'm not surprised. I may keep them and at some point send them off for proper lab testing, more just to satisfy my own curiosity, but given all the other "context clues" mentioned in the previous posts, I'm leaning meth.

Thanks. No idea why none of this came up on Google.
You used Google try a other seach engine

4-FA is not really MDMA lite. Methylone/ bk-MDMA might better fit that title.
It s a toned down Serotonin release, extending in a long lasting non functional stimulant.

That felt shitty start to end. It got really popular though. Not MDMA, or bk. Ime.
4-FMA is a bit better in that regard. Still nothing i would purchase more then once.
 
I'm uncertain if it's significant, but as far as I can tell, the immediate precursor to p-F amphetamine isn't a 'watched' compound and isn't legally controlled anywhere I could find, even here in the UK.
 
Sorry, immediate precursors since both ketones and nitropropanes are both legal. Why the latter is still legal, I really don't understand. I mean, some places even offer single isomers. I can't think of any other use for those.
 
Demand = supply? If that were true there would be good H in the streets still though -- above my paygrade I suppose haha
