Method KN (Potassium Nitrite) Method

[opro111]

would this just be "stump killer"?

I think that is nitrate not nitrite

Yes, I think you're confusing nitrATE for nitrITE, as Opro said!

 

[ayanitoolz]

Dimenhydrinate (e.g. Dramamine). It's the most potent of those options for sure.

Thank you so much for your kind words. I agree, and I find it a bit scary how many people might act out of fear rather than peace.

i thought that otc medications didn't work the same as anti emetics?

OTC medications aren't really on the same level as proper antiemetics. Things like dramamine or even benadryl can help with nausea, but they don't work the same way as prescription meds.

Prescription antiemetics like meto block serotonin or dopamine receptors in the brain and gut, which is what makes them so effective but some people don't have the privilege of being able to get them. So, OTC can be a backup in a pinch but definitely not a direct substitute if you need something strong or reliable!!

 

[TheEmptyVoid]

Firstly, I want to mention that I am not a medical professional, chemist, scientist, or anything of that sort. I'm just someone with a lot of free time and a passion for reading. I recommend that anyone seeking reliable and well researched, documented methods check out both the PPH and the resources in the megathread!!​

Potassium nitrite (KN), is a compound made up of potassium, nitrogen, and oxygen. It usually comes as a yellowish or white crystalline solid and is known for being a strong oxidiser. While it shares similarities with SN, KN is used far less often.

The reason I bring this up is that, as we're all aware, SN has recently hit its peak in media and government attention. Most suppliers have shut down, been compromised and/or placed under restrictions. The PPH (even as recent as the 2025 edition) indicates that other nitrites are being explored, with KN emerging as the next best alternative to SN. BUT please, never rush into a decision. Just because a method is getting more attention and there are more regulations doesn't mean you should hurry or feel pressured to act quickly out of fear of "missing your chance".

Here is the SS thread where you can get the 2025 pph​

Where It's Used Outside of CTB:
KN has a few niche uses. In metal treatment and heat transfer, analytical chemistry and in the food industry. These days, that use (food) is either banned or regulated, mostly because nitrites can form cancer causing nitrosamines when exposed to high heat or acid.

What you could say if asked why you have KN:



I'd suggest having evidence of these uses around, i.e. photography equipment or something. Else, you can simply say you don't have it, or it didn't reach you.

Where to buy KN?:
KN is actually quite easy to find. Just take a look at marketplaces on the clear net for 'Potassium Nitrite' or the equivalent term in your language. If your usual search engines aren't helping, I suggest giving another one a try! You really only need a small bag (like 100 g), but most sources I've seen sell around a minimum of 250 g. Just make sure it's Nitrite and not Nitrate!!! Make sure you purchase 98% or higher.

How to store KN:
Exactly like SN!
Store it in a tightly sealed, clearly labelled container made of chemically resistant material like HDPE plastic or glass with a screw lid.
Light and heat can cause decomposition. A locked cabinet or drawer in a cool, dry room is ideal. Avoid places with moisture (like bathrooms or under the sink or your car) and never store it near anything flammable or organic (like sugar, sawdust, or petrol).
Never keep KN in the kitchen, pantry, fridge, or anywhere food or drink is handled.

Stability of KN:
Source 1 - TLDR: Stable under normal conditions when dry, cool, and sealed.
Source 2 - TLDR: Degrades in high temps. Decomposes above ~350 °C, emitting toxic nitrogen oxides. Melting starts around 440 °C, with an auto-ignition point near 510 °C.
Source 3 - TLDR: If kept in sealed, opaque containers in a cool, dry spot, KN can remain stable for many months to years.

What Happens when KN is Ingested:
If KN is swallowed in a solution (identical to the one for SN), it can become dangerous quickly. The main effect is methaemoglobinaemia, just like SN. It is a condition where the nitrite turns normal haemoglobin into methaemoglobin. That sounds technical, but what it means is your blood can no longer carry oxygen properly.

Time Since Ingestion (minutes)	Likely Symptoms if Untreated
0 minutes	Ingestion occurs. No symptoms yet.
5 minutes	Rapid absorption begins. Metallic taste, sudden nausea, chest tightness, or lightheadedness.
10 minutes	Skin begins to turn pale or blue (especially lips and nails). Shortness of breath. Light confusion may begin.
15 minutes	Loss of consciousness probably around here. Cyanosis worsens. Breathing shallow. Headache, dizziness, and collapse are common.
20 minutes	Oxygen deprivation severe. Unconsciousness definitely by now. Seizures or vomiting may occur. Heart rate elevated.
25 minutes	Deep coma or convulsions. Respiratory function deteriorating. Risk of cardiac arrest increasing.
30 minutes	Very high risk of death. Without immediate treatment, survival is unlikely.

It's difficult to say exactly when the effects will begin for each person since everyone is different. This is just an estimate.

Lethal Dose:
So there are potentially two lethal doses.

1:
https://westliberty.edu/health-and-safety/files/2012/08/Potassium-Nitrite.pdf <- my source
According to West Lib, the LD₅₀ (the dose required to kill 50% of test subjects) varies slightly depending on the species, but they report an acute oral LD₅₀ of 200 mg/kg in rabbits.
To offer a rough estimate based on the 200 mg/kg figure, a 70 kg adult human would have an extrapolated LD₅₀ of about 14 grams, though actual fatal doses have been reported from as little as 0.7 to 6 grams in sensitive individuals or when ingested rapidly. You have to remember though, LD₅₀ doesn't just translate to humans!!!!
If we compare to SN, I'd say that if you are an average or below average body type, 25g is a good dose, and if you consider yourself larger, than 30-35g is a good dose.

Body Weight (kg)	Estimated LD₅₀ Dose (grams)
60 kg	25 g
80 kg	25 g
100 kg	25 g
120 kg	30-35 g
140 kg +	30-35 g

2:
The only research I have found for potentially needing a higher dose is in this book which says:

Which in dumb people terms means SN is 67% nitrite by weight and KN is 54% nitrite by weight so:


So if the normal SN dose is 25 g then to get an equivalent dose in KN, you'd need 31 g.

Then you'd be looking more at something like this:

Body Weight (kg)	Estimated High Dose (grams)
60 kg	30–31 g
70 kg	30–31 g
80 kg	30–31 g
90 kg	30–31 g
100 kg	40 g
110 kg	40 g
120 kg	40 g
130 kg	40 g
140 kg	40 g
150 kg	40 g
160 kg	40 g

↓Regarding why people need to care about dosage↓


The KN can be dissolved in 50ml of water. Stir with a plastic spoon, not metal! Also use a plastic cup. Make sure the KN is dissolved before consumption.

Scales:
As with SN, you need a jewellers scale with a 0.01 option. Something like:
https://a.co/d/aFYR1Uq
https://a.co/d/2MNvS6I

Reversing the effects of KN:
Just like SN, it's really important that you call your emergency department right away, let them know you've taken potassium nitrite (don't say KN because they honestly probably won't know), and inform them that you need methylene blue (pronounced Meth-uh-leen bloo) to help you survive. Making sure they get this information quickly could make all the difference.

KN Protocol:
Option1:
For the prior 48 hours, this is the regular protocol to follow provided by Stan for SN. It applies to KN, too.

Day 1	Medication and Dose
08:00hrs	1 X 10mg Metoclopramide
16:00hrs	1 X 10mg Metoclopramide
24:00hrs	1 X 10mg Metoclopramide
Day 2	Medication and Dose
08:00hrs	1 X 10mg Metoclopramide
16:00hrs	1 X 10mg Metoclopramide
23:00hrs	OPTIONAL: 600mg of Ibuprofen or 1000mg of paracetamol. You can use any painkiller as long as you stay within the recommended dose.
23:15hrs	3 X 10mg Metoclopramide (30mg in total)
23:30hrs	Double dose of what is recommended on the label of the antacid.
24:00hrs	KN drink.

Option 2:
If you prefer, this is the repurposed SN protocol from the 2025 PPH!


What does semi-reclined look like? Here is a really cool drawing I did:

OTC alternatives/Medication Sourcing help:

• If you're struggling to get access to metoclopramide, alternative options available OTC are: Meclizine (e.g. Bonine, Antivert), Diphenhydramine (e.g. Benadryl), Dimenhydrinate (e.g. Dramamine). Else, there are online international pharmacies you can use to source antiemetics.
• If you're struggling to get access to propranolol, there are no real OTC alternatives. But beta blockers are optional and iirc you don't really need them! Else, see below.
• If you are struggling to get access to oxazepam, there are no real OTC alternatives as its a benzo. I recommend looking at this thread for absolutely no particular reason: https://sanctionedsuicide.site/threads/how-to-access-dark-net-markets-for-ctb-resources.106130/ It is mostly up to date. You can also look at using Brave browser which has an inbuilt Tor connection. Use this at your own risk!
• If you're struggling to get access to an antacid, alternative options available OTC are: Tums, Rolaids, Mylanta, Gaviscon, Maalox, Milk of Magnesia.

Here's extra stuff if you want to read about KN yourself:
Toxicological Profile for Nitrate and Nitrite. (this is the one for the second dosing theory above)
Re‐evaluation of potassium nitrite (E 249) and sodium nitrite (E 250) as food additives (this is a big one, so I reccomend ctrl+f and searching key words)
Potassium nitrite (compound)
Good old Wikipedia

Okay, thanks bye!

OMG I found this method you saved me from hell, now I can use this method since sodium nitrite is blocked in my country but potassium nitrite is not <3

[nobodycaresaboutme]

thank you great information and drawing! this will help many of us who cannot obtain SN and access the relatively peaceful way out due to stupid government restrictions. by the way, i feel like an idiot but i have a question. why is it not "PN (Potassium Nitrite)" like "SN (Sodium Nitrite)" but "KN"?

Oh, it's just because the chemical symbol for Potassium is K, not P! It comes from the Latin name Kalium, so Potassium Nitrite ends up being KN. Same reason Sodium is Na (from Natrium), so Sodium Nitrite is SN. It's one of those weird chemistry things lol.

I thought that if chemical symbols define shorthands, sodium nitrite would be "NaN" or "NN"

shorthands	chemical symbols	English names
SN	NaNO2	Sodium Nitrite
KN	KNO2	Potassium Nitrite

It seems my brain doesn't comprehend it yet... Anyway thank you for your explaination!

[starvingsparrow]

[gothbird]

I haven't come across anything on the forum yet. It's just a theory suggested in the PPH that other nitrites might work similarly to SN. They also mention lithium nitrite, among others.

Shame. It does sound promising if the info here is true, especially as SN is now apparently quite hard to get in the uk/eu. But until we have confirmed cases in practise, I wouldn't want to recommend that anyone be the first guinea pig.

 

[Depressed&Stressed]

Zofran is hands down better if you can get it. It's the gold standard antiemetic in medical settings and used specifically for powerful chemical nausea.
But if you can't access it, dimenhydrinate is still better than nothing and can help.

What kind of protocol should I use with Zofran prior to taking the KN solution? The highest doses I can as often as I can for 48hrs prior to taking the KN?

Treat it much like SN!
If you want to do 48 hours, which you really don't need to, you could do something like 8 mg orally every 8 hours for 48 hours prior.

 

[Busridin'26]

From the lil bit I've read about KN & with depressed/ starved brain capacity apologize for "dumb" questions.

Is there a risk of storing and it exploding?

Is the pain level & protocol really similar to SN(Seeems like it from reading)

And how does one test KN?

Sorry if these are previously answered. Have read megathread but brain & yeah.

 

[Depressed&Stressed]

Treat it much like SN!
If you want to do 48 hours, which you really don't need to, you could do something like 8 mg orally every 8 hours for 48 hours prior.

So trying to make sure if I've got numbers and times right. For KN instead of SN as a person weighing 53kg I would want to take 8mg of ondansetron (Zofran) every 8hrs, take pain meds an hour before, 45min before take a triple dose of ondansetron (?), 30min before take a double dose of antacid (OTC for me), then take a solution of 31g of KN in 100mL of water, then a bunch of lorazepam (only benzo I have) in some water immediately after downing the KN drink. Theoretically that should be a pretty peaceful passing?

Hi all. I wanted to mention that I was able to be prescribed Odansetron (Zofran) without asking for it or even knowing what it was. I was having issues with feeling stomach upset and nausea for about three mornings in a row, Peptobismo wasn't helping, and I asked my doc if he could recommend something. Next thing I knew, the pharmacy told me I had some Odansetron waiting for me.

What I guess I'm getting at is that reporting symptoms similar to mine to your health care provider may be all you need to do in order to get an Rx. :)

Oh good thinking to note that for others!!! Yes, ondansetron is extremely easy to get your hands on :) everyone I know that's ever told a doctor that they're suffering with nausea is given a bunch of ondansetron first. It doesn't even need to be primary care, you can go to urgent care and get ondansetron. I honestly don't know why it isn't mentioned in any of the antiemetics or alternatives considering the fact that ondansetron is a pretty easy and effective prescription antiemetic to get your hands on in comparison things like metoclopramide. The prescriptions for me also have always been incredibly cheap, less than three or four dollars usually.

Because meto speeds up the emptying of your stomach, which allows things like SN to be absorbed faster, and is more effective at preventing vomiting.

Ondansetron is a great drug with less side effects, but it's not as effective. Though definitely more effective than OTC nausea drugs.

The gold standard is 30mg meto + 8mg of ondansetron together.

Thank you for the more in-depth explanation of why you want which drugs!!

 

[Linda]

I would add that sulphites (not sulphates) also scavenge oxygen from solutions, i.e. they work in the same way as SN. I have no information on how effective they would be for ctb, but someone might like to research the topic. Sodium sulphite, at least, is stable for years, provided it is kept dry and in an airtight container.

 

[idiotmother]

Shame. It does sound promising if the info here is true, especially as SN is now apparently quite hard to get in the uk/eu. But until we have confirmed cases in practise, I wouldn't want to recommend that anyone be the first guinea pig.

There is a thread of two girls doing KN together and they were successful. I also remember a thread of another female attempting KN and being unsuccessful.

 

[SomedayorNexttime]

How do you use it to CTB with a mixture?

 

[Ariel1]

This sounds painful.

 

[CTB set me free]

There is a thread of two girls doing KN together and they were successful. I also remember a thread of another female attempting KN and being unsuccessful.

It would be way easier to do with CTB buddy imo. Do you know why the one was unsuccessful? I'm guessing probably early medical intervention.
