Dose - K quantity in ampules

[Niteflights]

I am a bit confused over how to determine the total amount of ketamine in a given ampule. I see two varieties:

Ketamine inj 100mg/2mls

Ketamine inj 5mls/250mg

Can someone clarify exactly how many mg of ketamine would be in each ampule?

Cheers,
Niteflights

It can be confusing, especially as ketamine can make numbers and even words hard to fathom!

As far as I can see, 100mg/ 2ml is the same as 50mg/ 1ml-- meaning you inject 1 ml for every 50mg you want. Simple.

If I am not mistaken, the second is in fact the same: 250mg/ 5 mls= 50 mg/ ml.

Some ampules are 100mg/1ml-- probably for horses not cats!

Some ampules are 100mg/10ml (was the 100mg/1ml a typo?)...
The 100mg/10ml is the one SWIM is quite familiar with. I'm just taking his word for it! SWIM hopes he helped clear this up as the 100mg/10ml is what is known by some as "Super-K".... the one most seeked out by ketamine users out there!~

...yet...then again...maybe the 100mg/1ml wasn't a typo and SWIM simply hasn't stumbled into any of such strength..

[enquirewithin]

It's not a typo. SWIM has never seen 100mg/ 10 ml.

Unless he is getting confused, that would mean a K-hole-type, dissociative dose would need 10 ml of solution of more.

SWIM had pharmaceutical bottles of ketamine, for human use, containing 5mg/ml.

The hospitals must use large syringes! Nice pix.

[freedomordeath]

In india its for sale in the chemist...when you buy 3 bottles you get a free spoon!
most people poor the little inj bottle on to a big spoon and then heat it untill it becomes white powder...1 small bottle would send you I guess it must be like 100 mg of white powder...after heating...so if you sniff that at once...you will be among the stars for at least an hour...I think its too much to take at once and swim mostly took about 2 big ones out of 1 bottle...be carefull dudes...by the way I think its horrible stuff..;but swim liked it a lot

[DJ]

oh...duh...guess SWIM had it mixed up...this was what he was meanin' w/o looking at the bottle... ...oh well....

WTF, 5mg/ml!!!

Surely they are not made to be used for anaesthesia (or recreational use).

[adzket]

in swims exsperiance 25mls is = 1gram aprox if you utfse you will find some info on exsact conversion rates another swim of mine gave some time back there is also probably alot more out there from other swims.

Ketamine do not come in 'exsactly' uniform solutions. One brand can easily be twice the strength of another per ml, or more, as this thread discusses. UTFSE might inform you.

Asssuming that all brands were the same could be dangerous.

True. If you believe the dosage printed on the lable, multiply # ml's of fluid time listed mg/ml value. Therefore, a 10ml bottle with a listed potency of 100mg/ml would be

10 ml * 100mg/ml = (1000 mg) * ml
--------------
ml

The ml's cancel out and you're left with 1000mg or 1 gram.

That said, the potency listed on the lable could be wrong. In which case, if one were keen to find out the specific amount of Ketamine is a given bottle, one could evaporate the liquid and weigh the crystals. These crystals could also be dissolved in the appropriate amount of distilled water to return to original form.

Considering that Ketamine is very, very safe dosage-wise (with OD levels hundreds of times higher than recreational dosage levels,) using the word dangerous here is a bit inflamatory. Assuming all brands are the same strength is almost certainly wrong, but probably not all that "dangerous" per se.

When SWIM boiled down his ketanest, he found out more than half of the total weight was conservatives, so this isn't very accurate.

[Beltane]

First, you can just let K dissolve. Unless you're in a hurry, no reason to boil.

I was under the impression that whatever crystals are left after evaporation would be pure K crystals. If not, then I guess I'm wrong.

What's a "conservative?" And how would you know how much of what's left after evaporation is K and how much is this conservative stuff?

Please give specs on the bottle you're referring to above. How much liquid in ml? What is the listed potency in mg/ml? How much was left over after boiling exactly? What was this matter specifically? And how was this determined and/or measured?

Thanks-

I might be mistaken,but I thought 100 ML would get swim about 1 gr in powder after evaporating the water

swIm rememberrs getting small bottles for injection,burning the water off and from a small bottle .;about 2 massive snifs of pure K would be left.
Swim thinks its almost impossible to od by sniffing this..your nose would be totally blokked after sniffing half a G anyway .
but never ever combine with alcohol.;that is very dangerous and it will make swiy feel awful

[Psych0naut]

SWIM didn't want to wait for ages, and when carefully boiling down on a hotplate, no ketamine will be burned or damaged, see this.
SWIMs ampoules contain sodium chloride and a lot of benzethonium chloride, benzethonium chloride is a conservative, and this is of what seems to make up a lot of the weight of the powder when boiled down.
If SWIM boiled a bottle of 20ml 5mg/ml solution, than it should contain 100mg of ketamine, if after boiling down, the total amount of powder seem to weigh something like 180mg, than it's logical that the rest is the conservative.
When snorted, it doesn't burn or taste like salt, so the sodium chloride is just a very small percentage of the total weight, so the rest must be benzethonium chloride.
The bottles SWIM boiled down where Ketanest bottles, each contained 20ml of 5mg/ml s-ketamine, SWIM doesn't know the total weight of the powder anymore, but it was something like 2300mg, of which 750mg was the s-ketamine, SWIM weighed it on a scale accurate up to 10mg.

[freedomordeath]

Very interesting.;maybe thats why the nose get blocked.;swim wonders how to get the pure K out

[Psych0naut]

Acid base extraction. Indeed SWIM also had the problem of having a stuffed nose before he could snort all the ketamine, really irritating.
The most he could get up his nose of pure ketamine was 500mg, and he had space left for more, and SWIM doesn't have a big nose

[enquirewithin]

SWIB's equation looks exactly right.

Considering that Ketamine is very, very safe dosage-wise (with OD levels hundreds of times higher than recreational dosage levels,) using the word dangerous here is a bit inflamatory. Assuming all brands are the same strength is almost certainly wrong, but probably not all that "dangerous" per se.

True, in terms of fatal overdose, ketamine is safe enough. Accidentally taking, say, 2 to 4 times the intended dose is very unlikely to cause any life-threatening situation, unless you are too near a swimming pool or a bath, but getting into a state of general anesthesia when you are not expecting it certainly can cause accidents!

Niteflight:

Quite simple:

100mg/2ml amps contain 100mg Ketamine in 2mls of liquid.
250mg/5ml amps got 1/4 of a gram!
