What is the street value of a lethal dose of Fentanyl? My dealer is asking how much I want to spend?

I dont know much about street value but Ive seen 500mgs of it go for 40 dollars on the darknet so maybe it's around that area?

For someone with no tolerance like you and plus the weight I think you can say 5mg is an unsafe amount? It's always best to go beyond 10mg. When I do decide to get Im taking the full 500. Also you have to know that some street fent doesnt come pure so it can be less effective in small amounts.

Depends on purity which you won't know. I've seen 15mg recommended here.

My suggestion would be to ask around, but framed in a harm-reduction lens:

"What is the highest dose of fent I could do before it becomes deadly? I don't want to OD and die just trying to get my fill."

And ask several people. Most drug addicts will have anecdotal stories of almost dying or their friends dying. It's good to get a consensus.

Are you injecting or snorting? I have a needle but have never shot up before and can't see my veins well.


How much is 15 mgs you thinking?

I think I'll be snorting I looked into IV it kind of seems easy but still difficult because if I do miss a vein it'll go into my skin which will still get absorbed but not as effective.
IV is immediate while snorting will take a few minutes to start the effects. You can squeeze really hard to see your veins pop up if you struggle seeing them.

If you trust the guy and he told you it's really pure fentanyl then I think 15mg might be enough but it's always safer to get more just to compensate. Street fent can always range in purity.

Read this from the DEA :

It says domestic is usually 14% pure. I'm assuming they mean here in the U.S. That means if you got 15mgs of 14% pure fentanyl, do the math :

15 mg x 0.14=2.1 mgs of that 15mg is fentanyl while the rest 12.9 mgs isn't.

So the other 86% is just a bunch of fillers or other cheap drugs to add in weight.

Those numbers are fucking crazy.

This is just a stab in the fucking dark.

15mg is going to take a lot of water to dilute properly, it's a shit ton of syringes

Yeh I just saw this yesterday. I thought most fentanyl came in really pure because of the spike in OD's in the U.S but a lot of it isn't even pure fentanyl so it's safe to say anyone who wants to OD on fentanyl either needs to check purity with their vendor or a company like: https://energycontrol-international.org/drug-testing-service/
Or just take a lot of it to compensate as much as possible.

2mg is the lethal dose usually, given your body mass 3mg could do the job, but if you want guaranteed death, anything above 10mg is virtually impossible to survive without medical attention.

Ok, I hate to piggyback but I and for this very answer. Except I am a HEAVY user with high tolerance. Most around here is cut with fent/tranq. I'm 215 lbs. Will 10mg be enough to ctb, even if the calculations above are accurate?

What's this guy talking about then

"Even with preferable routes like IV or per rectal, it will be challenging to absorb the dose fast enough. Significant amounts can be metabolized quite quickly by some users with higher genetic tolerance (more enzymes, differences in cardiovascular processes like bloodflow, absorption in fatty tissues, antioxidants which break down the active substance, and carrier proteins/ligands which can carry the drug away from active binding sites in the brain). Also, syringes can only dissolve so much substance, meaning a lot may get clogged up or simply not end up in the bloodstream.



As I mentioned in the OP, 2 grams are likely to still only contain a few milligrams of active substance due to either cuts in street derived product or pill fillers from pharmeceuticals so the actual dose will be far smaller than it appears at face value.



I still retain the fact that opioids will never be more than low to moderately reliable even with these fail-safes/good practices.



SN is always a better choice."

15mg I'm a 1 cc syringe is not a lot. Typical H doses for regular users are in the 70-100mg range (and I'm talking about brown, which is insoluble in water without an acid).

Even accounting for impurity you're talking 15/2.1 * 15 = 107.4mg total solids. Given fentanyl salts solubility of 25mg/mL it's not infeasible it would dissolve completely in 1cc. Depends on the cut, but if it's insoluble it'll be left behind after filtering. A 2cc barrel would be no problem.

I wouldn't advise anyone to use strong opiates for any non-medical reason, but the math is mathing even at 14%.

is fent overdose an easy death?
  • Opioids like fentanyl bind to receptors in the brain that regulate breathing.
  • When fentanyl binds to these receptors, it disrupts the signals that tell the body to breathe.
  • This can lead to slowed or stopped breathing, also known as respiratory failure or respiratory arrest.

I mean you stop breathing, how comfortable do you think it is? Ha

It really depends. Some people do well on opioids and feel the high, some get absolutely fucking sick from it

of course, hense the quotations lol. but i was under the assumption when you overdose, especially on opiods, you're so high you kinda either don't really care or you lose like real consciousness. and the discomfort you'd normally feel from being unable to breath wouldn't be so prominent.

Like I said, I wouldn't advise anyone to use strong opioids for non-medical purposes. I just wanted to correct the inaccurate information. You'll need to do your own research.

It is painless if you are not found and if you are successful. Willing to combine brains on this
