I have been offert this as testing samples. Unfortunately I cannot find any info about it in the net. Maybe here on Bluelight somebody has already experience with this cathinone deratives? I do not wonna be a complete guina pig. I guess effects are simular to other cathinones, with dosages from around 20 to 200 milligrams. But that is still a wide range, depending if it has supposed stimulant or empathogenic effects. With metylone you have to dose around 200 mg and with NEB you have good effects around 50 mg. But there is stll MDPV wich starts to work around 5mg. I guess you will tell me to leave it or start with an allergy test and then go slowly higher with the dosages. Still I would like to collect some information if it is out there. I guess 4 metyl-pentedrone is still simular to Pentedrone, mainly stimulant, but who knows. 4-mbc or benzedrone (stuped name) is supect has stimulant properties too. I have read it has be found in some legal "bathsalts". But also no informaion out there. One has always to be the first to test a new RC but i do not wonna ingest a chemical that has supposed severely neurotoxic properties like Brephedrone. I guess it is not the case with this two chemicals, but who know. Maybe somone here has already experience with tis two, or some chemical experts can shed some light how this chemicals are working?.
The third chemical I was offered was bz-6378 or 4MeMapb, which I read is rather crappy,, simular t o etylopuphedrone I guess. So maybe if you have any infos on how this chemicals act and in which dosage range, I would appreciate that!

If anyone knows anything about these substances, or has tried them, it'd be the mysterious chemists of ADD. I'll send this their way since these RCs are pretty darn obscure. If they turn out to be empathogens like methylone, then ultimately they belong in PD.
 
I only know that 4-MBC is very shitty stimulant. And that comes from a chemist who tends to overdescribe and overrate substances (cheers btw).

Funny enough, everybody knew about 4-BMC to pBA relation, but nobody wanted to see 4-FA relation to other halogenated amphetamines. IMO that was kinda very unappropiate from bluelight users to bash on a substance (4-BMC) while like half of the forum uses related compound 4-FA and doesn't care.

It is a generally accepted fact that 4-FA is far less neurotoxic than the other halo-amphetamines.

Careful now, guys. 4-MBC ("benzedrone") is not the same substance as 4-BMC ("brephedrone"). 4-MBC is 4-methyl-N-benzylcathinone, which is presumably a prodrug for 4-methylcathinone (again not to be confused with 4-MMC, mephedrone). I would expect 4-MBC to have a slow onset, low potency and probably long(ish) duration of action compared with mephedrone.

I can't believe what kind of crap the RC suppliers are putting out these days. :(
 
I did not want to start a fight here on which RC is more neurotoxic than others;). They are all risky, but in my experience they rather lead to pysical problems. I never felt totally ruined or burnt out like after the use of MDMA even after daylong Mephedrpme binges. The physical problems were much more worrysome. But itś good we have experts on bluelight who can tell you about neurotoxidity and risk of new RCś. Thanks for the info on 4MBC Limitbreaker a shitty stimulant is not really what I am looking for. Maybe 4-metyl-pentedrone has some potential, if it is anything like pentedrone, which is O.K.

Do yourself a favour and start really low with the 4-methylpentedrone. The other valerophenones (pyrovalerone, MDPV, pentedrone, pentylone and a-PVP) are all active in the 5-10 mg range, and you do not want to overdose on this class of compounds. I don't touch RCs anymore, but I used pyrovalerone back when it was available as a pharmaceutical drug in certain European countries. 5 mg would produce slight stimulation, 10 mg would get me all jittery and anxious (I'm a girl and didn't have any stimulant tolerance at that time). I didn't care much for it, really. I would expect 4-methylpentedrone to be a straight NDRI like pyrovalerone. It's probably somewhat less potent than pyrovalerone, because 4-methylpentedrone has got a methylamino group where pyrovalerone got a pyrrolidinyl (ref. pentylone vs MDPV, and pentedrone vs a-PVP).

Please read my post right above yours. 4-MBC is not 4-BMC/brephedrone, which I think Limitbreaker is confusing it with. 4-MBC might still be a shitty stimulant for all I know, but let's try to keep things straight, mmkay?

EDIT: I read the thread again and I realise I may have misunderstood what Limitbreaker wrote. My apologies!

Well pentedrone and pentylone are not as risky as MDPV. And the typical dosages with Pentedrone are much higher than with MDPV, like 50 or 80 milligramms. Still, when you overdo it with the pentedrone during a session you will still end up as a nervous, sweating, restless wreck. But that coming down is tolerable and you can sleep the same night, not as I expect it with MDPV. Nevertheless one should play it safe and start low. Maybe the methylated Version is much stronger than the normal pentedrone. I have never used MDPV, coz I read all that scary trip reports.
 
250 mg pellets of pentedrone sounds absolutely fucking insane. There's a thread in OD in which one member was "experiencing incredible euphoria" from 7 mg pentedrone. And there's a trip report where someone stayed up for 4 days straight on pentedrone, but the poster doesn't specify the amounts involed. Of course we don't know if pentedrone was what they were really taking. RCs are like a box of chocolates, you never know what you're gonna get.

I wouldn't be so sure that the 4-methyl rule holds true for the valerophenones, they're an odd bunch.

4-methyl-pentedrone ?

in many cases 4-methylation decreases the potency:

methcathion (70mg) -> 4mmc (200mg)
amphetamin (50mg) -> 4ma (150mg)

i have seen a vendor offering 250mg-pellets of pentedrone. if we get the same decrease in potency after 4-methylation then this could be a very weak compound.

be careful with that assumption as on the other hand enlongation of the alpha chain increses potency down the same line: MC-->buphedrone---->pentedrone
 
yeah, one has to be carful with this new drugs, better start low when testing. So this 4mbc seems to be a prodrug that is converted in the body into a mephedrone like sunstance. Cracy how they try to find some working new replacment.
Well actually I am in the RC Scene long time enough to know the dangers of unresearched chemicals. Never ordered anything that has not be tested by anyone else, but its free and I am unemployed. Will be carful. Actually we have some new cracy law in Austria that outlaws basically everyhing with whole Substance groups . But there is no Punishment for costumers, only quite severe Punishments for shops as long as they are in Austria. So as long as you don't get caught by customs or the police you can still enjoy RCś, and if they catch you, they can only take it away from you. Fuck the Goverment. I switched to legal highs, coz i was caught a few times by the cops for smoking weed as a young adult, and hat to take drug test for 2 yeas. Also I rather trust RC Vendors than street dealers. But that is fucking politics and does not belong here;)

unless it was me who posted i too got an incredible numb feeling all over my body and an euphoric rush from 7mg of pentedrone from a very reliable source.

pure white fluffy sticky stuff
 
My dog bought 500mg and split it into fours, so each dose was 125mgs. My dog took it orally and it lasted about 3 hours. Had lots of fun!! If you are doing it any other way than you might have to wait for a different answer. My dog wont insuflate due to sinus problems. My dog seems to think that orally is better because it lasts longer. Good luck and I hope that this helps.

quit giving your dog research chemicals it's not even like they have a similar metabolic system
dogs can't even talk so it's obvious that you are your dog
