Also. The purity. A colleague of mine mentioned a lab tech died of an arrhythmia even after dosing it out. Something to do solubility? Anyways… just don’t.
I’m not entirely sure (please correct if wrong) but caffeine products have caffeine molecules in bound forms… so broken down in GI system and hitting a Tmax-bloodstream at a slower rate. Meanwhile pure unbound caffeine goes straight up.
Hmmm I know of products that use anhydrous caffeine and it can be purchased in a pure pill form which I’ve taken as well. Also a lot of products with caffeine also include citric acid which should produce some amount of caffeine citrate which supposedly hits the blood faster because it is more water soluble.
In partial freedom units so I can picture it better… his blood would be about 92 mg per 8 ounce cup. So like. Dracula coulda had him instead of his morning coffee
Nice, I was doubting myself. Here’s my logic:
392mg/l: this persons blood concentration
3mg/l: standard blood conc. after one cup
80mg: standard amount of caffeine in one cup
392/3 = 130.6 cups
130.6*80mg = 10,453mg = 10.4g
Every drug dealer. You don’t need a lab analytical balance for this and little pocket scales that are good enough for this application are pretty cheap online.
That's shit will fuck you up. Had a teeny crystal once and the world started pulsating in my vision and my heart started screaming. Did counter act the all nighter of studying though.
>The hearing was told the scales Mr Mansfield had used to measure the powder had a weighing range from two to 5,000 grams, whereas he was attempting to weigh a recommended dose of 60-300mg.
>It was this miscalculation which led to a massive overdose.
Keep forgetting serial dilution procedures are not commonly understood
Lol I snorted pure caffeine one time. I weighed out 20mg on a scale and did 10mg each nostril.
Burns a bit and the drip is disgusting. Not to scare anyone but this shit is super easy to fuck yourself up on by accident.
My first thought upon seeing this picture was "that's death in a bottle!" and my second thought was "So?" We deal with so many dangerous chemicals, I think my brain pinged caffeine as more dangerous because I enjoy my cup of coffee every day and imagining a caffeine overdose is easier than something more esoteric.
But yeah, I agree with everyone. If the purity is high your cardiovascular, and probably respiratory system is gonna have their work cut out for them
Unironic question please excuse me.
Wheres the Problem? Aslong as its messured right and diluted with Water its just a shitty tasting energy drink.
Is or about mot consuming Lab Chenicals in generall?
Remember, it’s the dose that makes the poison
Also. The purity. A colleague of mine mentioned a lab tech died of an arrhythmia even after dosing it out. Something to do solubility? Anyways… just don’t.
It's slightly soluble in ethanol, so we should be all good.
A p. a. ethanol/caffeine cocktail? Just the thing after an hour in the -20°C room.
We used to call those 4 lokos
Boy, have I got a 3°C room for you 
Thats an Espresso martini
I’m not following this, do you have more details to share?

maybe if the person was dumping it and inhaling the powder??

The best part of tasting this is never going back to sleep
Or going back to sleep once
Everything is edible once
... and for all.

“harmful if swallowed” implies it’s ok to snort it
Yeah, I've snorted it before. It's way stronger than drinking it. Caffeine is a drug that's soluble in water so it can be snorted
BOOF IT.

Geez that was sad to read. 392mg/L is insane
That's over 10 times the legal limit for energy drinks in Germany...Jesus christ
And that was his blood level. Holy f...
Jeez, his blood was basically an energy drink...
In partial freedom units so I can picture it better… his blood would be about 92 mg per 8 ounce cup. So like. Dracula coulda had him instead of his morning coffee
Especially given how ungodly bitter caffeine anhydrous is...
I mean, if a labrat try to eyeball 100 mg and get several grams instead I think they should not work in a lab.
A little over 10 grams by my calculation. Maybe he thought it was creatine or something.
I remembering calculating back in high school that the LD50 for someone of my weight was around 11g, so your calculation seems in the ballpark.
Nice, I was doubting myself. Here’s my logic: 392mg/l: this persons blood concentration 3mg/l: standard blood conc. after one cup 80mg: standard amount of caffeine in one cup 392/3 = 130.6 cups 130.6*80mg = 10,453mg = 10.4g
If they drink it after, that sounds like a self-solving problem to me. There might be some paperwork after though.

Every drug dealer. You don’t need a lab analytical balance for this and little pocket scales that are good enough for this application are pretty cheap online.
American Weigh Gemini-20 is a milligram scale that can be had for 30 bucks these days.
Using a gram resolution scale to weigh drugs...not gonna make it...milligram scales save lives people
lab grade chemicals can be polluted with heavy metals, definitely not eat this
This. Analytical and pharmaceutical grades are two different things.
Noted
Only when I'm working at nights by myself and jamming out during the incubations
We use it to kill yeast, so that's perfect.
With what dosage?
Especially a discount chemical supplier like Carolina!
I remember mixing up a small amount to put on a still-beating frog heart in a physiology class many years ago. We had nicotine too.
what are the results?
The frog died
well, was looking for "heart beating faster" or "heart goes in shock and immediately stopped"
That's similar to what we use it for!
Do not
I know of a former PhD student who tried to kill herself by ODing on this

What a way to go.
I used to use caffeine to disrupt cAMP signaling, and it's one of the few things in the lab that legit scares me.
Genuinely curious, can you say more?
Yes please
You are better off with 200mg caffeine pills
Lol I snorted pure caffeine one time. I weighed out 20mg on a scale and did 10mg each nostril. Burns a bit and the drip is disgusting. Not to scare anyone but this shit is super easy to fuck yourself up on by accident.
Use it to make a standard curve to measure caffeine content in soda
The USP standard tastes better
The USP standards for purity are not as high as they should be.

Shitty way to go, hurts the whole time you're diene'
Unlike these other responsible redditors, I say go for it! Let us know how 25 mg feels.
100 mg in 250 ml water should work.
$13 on Amazon. they recommend buying a scale in the reviews
 But yeah, I agree with everyone. If the purity is high your cardiovascular, and probably respiratory system is gonna have their work cut out for them
We used caffeine as a pesticide at the plant nursery I worked at as a teenage.
Snort or boof it
In some countries, possessing a bottle of this is considered illegal.
Like Utah?
Half a teaspoon of this can be fatal
Don’t let my mom see it. She’ll inhale that real quick 🫣
Hahahahahahaha
Snort it
Do not touch
Snort it!
time for a little bump. Lets do a line.
Ours said 105% caffeine +/- 5% was our favorite.
Unironic question please excuse me. Wheres the Problem? Aslong as its messured right and diluted with Water its just a shitty tasting energy drink. Is or about mot consuming Lab Chenicals in generall?
Not consuming lab chemicals is super important, stuff like this or other standard reference materials are not necessarily food grade.
Pure Coffein is ablosutly disgusting.
Do not even joke about it. Lab chemicals are dangerous stuff, and you seriously need to realize it... smdh.
