Skip to last sentence if you do not care about the background story and just want to quickly help with my question.

OK before anyone warns me. I know this will be a very concentrated solution. I live alone in my apartment no kids no pets no 1 to accidentally dose it. I have social anxiety disorder and have a legit prescription for Xanax 90x 1mg pills per month. I have no insurance and I can't afford 90 dollar doctor visit plus another <snip - lots of money> for the pills. That's <snip - an expensive amount> a month just for my anxiety. So I found a Chinese supplier and got 10 grams of pure alprazolam for <snip - a low price> + shipping (and it actually weighed 11.4g so ty China for the fat sack). So for the price of 1 month I now have enough Xanax to treat me for many years.

Now I cannot find this information but I need to know the exact max solubility of alprazolam at room temperature (75F or 23.89C) in 100% pure propylene glycol. I have a 4 ounce (120mL) Air tight seal dark amber (94% light blockage) glass vial and a 1mL calibrated borosilicate medicine dropper with specially calibrated bent tip that provides 1mL per 20 drops. It also has lines on it that go in 0.1mL increments up to the 1mL it holds. I want to leave an ounce of empty space so will only be filling it up with 90mL of propylene glycol. Since 20 drops = 1mL I would like to get the concentration up to 20mg per 1mL so 1 drop = the same as taking a 1mg pill. If 20mg per 1mL is not possible because the PG solvent isn't capable of holding that much then I'd be willing to go to 10mg alprazolam per 1mL of PG solvent which would give me 0.5mg per drop. If 10mg per 1mL is not possible then I could go to 5mg per 1mL which would be 0.25mg per drop. That's really the lowest concentration I would go. so for 90mL of PG I need 450mg of alprazolam for 5mg/1mL solution (0.25mg/drop) or 900mg of alprazolam in 90mL PG for 10mg/1mL solution (0.50mg/drop) or 1800mg alprazolam in 90mL of PG for 20mg/1mL solution (1mg/drop).

So I know exactly what I want to do. I have all the ingredients here. I just would like some concrete solubility facts before i proceed. I don't want to mess up anything and waste anything or dose it wrong. Hopefully PG can hold at the minimum 20mg/1mL more would be fine too. If I end up having to dose it as 10mg/1mL or 5mg/1mL I probably will just use the 0.1mL increments and dose 1.6mL if 5mg/1mL concentration or 0.8mL if its 10mg/1mL concentration as it won't be worth the hassle of counting drops but with the 1mg per drop 20mg/1mL concentration counting drops is the way to go and is the way I'd like to do this. I have THIS milligram digital scale. The Jennings / JScale JS-VG20 Digital Pocket Scale has 20 gram capacity with a 0.002 gram resolution. I know this scale is not accurate enough for anything below 10-15mg so I can't use it to measure my doses straight from the powder but for the amounts I'd be weighing to dose in liquid form (450mg or 900mg or 1800mg) it's more than accurate enough. I'd say anything that's dosed at 20mg or above it's accurate enough to dose right from the powder but Xanax does not fall in that category hence why I'm doing liquid dosing.


So the main question of this post is.. What is the maximum solubility of alprazolam in room temperature (75F 23.89C) 100% pure pharmaceutical grade propylene glycol? Preferably in the format [MAXIMUM mg of alprazolam able to be dissolved/1mL PG] I need it to be able to dissolve AT LEAST 5mg/1mL but would prefer greatly 20mg/1mL. Please somebody out there has the answer I need. You will be helping out a guy with social anxiety disorder that can't afford to see the doctor and pay for scripts. Also I know both of my ingredients are totally pure got the propylene glycol directly from the pharmacy I work at, it's the purest pharmaceutical grade you can buy. And the alprazolam is definitely pure, I blacked out for 12 hours off the tiniest little bump snorted (this stuff is impossible to eyeball or weigh properly [unless you have a multi thousand dollar laboratory milligram scale]) and the lab testing sheet that came with it indicated 99.998% pure alprazolam so I know my starting ingredients are exactly what they say they are so I don't have to worry about an impure starting point messing it up.

-sigh- I can't believe that there is no information on the max alprazolam PG can fully dissolve at room temp. Why am I not allowed to know this :/

Yeah, it's weird, I've looked for this before too and couldn't find any concrete numbers anywhere either. I've only seen a Rx solution with 1mg/ml and some experiment where they dissolved 4mg/ml. (I also read somewhere that it was apparently actually more soluble in a mixture of PEG and water than PEG (or water obviously) alone).

I'd say you'll have to experiment (and please let us know your results). Why do you want a 20mg/ml solution though? That gives you a really low margin of error with dosing.

I'm also doing this and would like to know the solubility. I'm planning to do 5 mg/mL, it should work right?
 
well i really didnt wanna waste my powder experimenting with different solubility levels. theres no way in hell im the first person in the world to do these experiments. It would be nice if someone could share their expertise so im not wasting alprazolam. in another note i took the tiniest bump of powder and its still too heavy a dose. xanax is so impossible to eyeball in pure powder form
 
Thats easy to find out, measure a quantity, dissolve it all, keep adding slowly to saturation, vacuum filter (büchner), wheight and you do the math.
Don't forget that the temperature and pressure will play a big role here, varying from day to day.
Of course I could retrieve the standard data from the tables, but it wouldn't be so fun then. =)
 
it's just annoying cause i know 100's of people on this forum have dissolved xanax before. Be nice if someone spoke up.
 
if i could get pure alprazolam omg the world would be in trouble i black out and go ape shit crazy on the real high doses like 100mg or more

almost 99% of alprazolam in the U.S. and UK is prescribed, so why would anyone need to dissolve their pills if they already come in pills?
 
sigh, i was tripping on LSD, but my post still makes sense. you said you felt annoyed because no one is speaking about dissolving alprazolam in propylene glycol, but in my post, i am claiming that your feelings are illogical and superimposed due to the fact that thousands of doctors in the US alone prescribed xanax on a daily basis. my question to you is, if you did have alprazolam pills that are accurately weighed and in almost exact doses, why would you want to dissolve the pills? that is why no one is "speaking up,' not because they want to hide their secrets from you, but rather because it is not common practice or knowledge.
 
Well at least I will be informing you about my results when I get the powder & PG. I'm not sure if the information of limit solubility of alprazolam in PG even exists.
 
I had some pure alp powder earlier this year, and found it easiest to simply touch the tip of a toothpick to my tongue, then touch it to the powder, allowing a tiny (like 1 or 2 grains of sand) to stick to the toothpick and then licking that off.
1mg is more or less a grain of sand.
 
What is the taste of raw alprazolam? Could you describe it as incredible bitter? I just did the dipstick method and even there were only some very small grains my whole mouth tastes very bitter for half an hour or so. I'm not sure if this is the taste of the ink (there happened to be couple particles of ink too because of my methods), and i'm not even sure if it's alprazolam.

Yes, you should expect a VERY bitter taste with pure alprazolam.
 
It would ruin my taste buds for about an hour. And yes dipstick method can be dangerous, I used extreme caution at every dose, but also (at the time) had a lengthy (18+months) daily xanax habit.
 
I successfully dissolved 750mg of alprazolam in slightly less than 75mL 100% pharmaceutical grade PG to end with a solution with a total volume of 75mL. 0.5mg per drop is a success. Stored in 4 ounce glass amber vial. Done paying doctor and pharmacy for my xanax. Good times :)

oh yea the powder is one of the worst tastes you could have in your mouth. I specifically drop the liquid all the way at the very back of my throat avoiding taste as much as i can.
 
I don't know the exact process, but i'm sure someone else does. I think you should lay the alprazolam onto blotter so you actually have dosage units.
